2.1 Basic safety instructions
The following basic safety instructions and warnings are an essential component of
these operating instructions and are fundamentally important for device handling.
Read the instructions carefully!
Make sure that you have carefully read these operating instructions and the
following safety instructions before setting up the device for operation.
Radio-controlled models are not toys in the usual sense. Assembly, installation, and
operation of the RC system require technical knowledge, care, safety-awareness
and responsibility. Errors or negligence can lead to considerable damage. Since the
manufacturer or the seller does not have any influence and control over the proper
setting up and operation of a model, such risks are expressly pointed out here and
any liability whatsoever is excluded.
A model that goes out of control for whatever reasons can cause significant damage
to property or personal injury. Be aware of safety at all times. Make sure to take out
general liability insurance.
Do not modify the radio control system. Use only original accessories and spare parts.
If the device is operated in combination with third-party products, ascertain their
quality and functional reliability. Each new or changed combination must undergo
careful functional testing, including a range check. Do not operate the device or
model if there appear to be any problems. First identify the error and troubleshoot it.
In particular, have the radio control transmitter and the receiver inspected at an
authorised MULTIPLEX Service Centre (see section 10.1 "Specifications" on
page 212) at regular intervals (every 2 to 3 years).
Operate the transmitter only in the permissible temperature range (see section 10.1
"Specifications" on page 212). Bear in mind that condensation may form in the
transmitter due to sudden temperature changes (e.g. warm car, cold environment).
Moisture may impair the function of the transmitter and other components of the
radio control system.
Safety instructions
PROFI TX
If moisture accumulates in electrical devices, immediately stop using the device,
disconnect it from the power supply and allow it to dry in the open state as far as
possible (up to a few days). Thereafter, perform a careful functional test. In case of
major condensation, have the device inspected at an authorised MULTIPLEX
Service Centre (see section 1.2 "Contact" on page 9).
Caution: static electrical charges!
In extremely dry air static charges tend to build up in the transmitter and / or the
pilot. The discharge takes the form of static sparking which can cause interference
or damage to the transmitter and other components of the radio control system.
Operation of the radio control system is allowed without restrictions within EU
territory and Switzerland.
Program a new model at home in peace. Make sure that the power system of the
model cannot start up unexpectedly. Check all functions carefully. Completely
familiarize yourself with the operation of the transmitter before putting the model
in operation.
Safety instructions
PROFI TX
Page 15
2.2 Safety instructions for the transmitter battery
The transmitter battery is responsible for the power supply to this device, and plays
an important role in operational safety. The charging circuit integrated in the
transmitter matches the battery. Do not charge the battery outside the device.
Batteries are not toys and must be stored out of the reach of children.
Damaged or defective batteries must not be used and should be disposed of
properly (see section 2.8 "Disposal" on page 22).
Do not heat, incinerate, open or short-circuit rechargeable batteries, do not charge or
discharge them at excessive currents, do not overcharge them, and do not charge
with reversed polarity. Take note of the admissible temperature range for the battery.
Mis-handling the battery incurs the risk of combustion, explosion, corrosion and
burning.
Safety instructions
PROFI TX
2.3 ESD notes for electronic sub-assemblies
The sub-assemblies of radio control transmitters (main circuit board, RF module,
Channel-Check module, Scanner module) are fitted with electrostatically sensitive
components. These parts can be destroyed, suffer imperceptible damage or have
their useful life shortened if static discharges take place (potential equalisation
through electro-static discharge) when the sub-assembly is touched.
The following protective measures are essential if you have to handle elec-
trostatically sensitive sub-assemblies:
Before fitting or removing such sub-assemblies, equalise the electrical
potential difference between yourself and your environment (e.g. by touching
a heating radiator).
Open the basic device and touch it over a large area in order to equalise the
potential relative to the base unit.
Do not remove any sub-assemblies from their conductive anti-static bags
until you have equalised the potential. Avoid touching electronic components
or solder pads directly. Hold the sub-assembly by the edges of the circuit
board only.
Once removed from the basic device, the sub-assembly should only be
stored in the conductive anti-static bag in which it was delivered. Never allow
the sub-assembly to make direct contact with a conventional, non-ESD
compatible container made of foam, Styrofoam or other plastic.
Safety instructions
PROFI TX
Page 17
2.4 Intended use
The PROFI TX transmitter is intended exclusively for operation of models by
radio control.
Always follow the switching on/off sequence in order to avoid any uncontrolled,
dangerous start-up of the power system:
Switching on
1. Transmitter
2. Receiver
3. Connect the flight battery or switch the power system ON
Switching off
1. Disconnect the flight battery or switch the power system OFF
2. Receiver
3. Transmitter
Assemble the model carefully
Install and adjust all control surface linkages in such a way that the surfaces
move smoothly and freely, and are not stalled even at maximum travel. Don’t
use the transmitter to regularly limit servo travels. It is always better to adjust
levers and pushrods mechanically and as thoroughly as possible. Avoid lost
motion (sloppy linkages). Use configuration options on the servo side of the
transmitter only for fine-tuning.
The measures mentioned above are essential in order to minimise the load on
the servos.This in turn allows them to perform at their best, and they will also
last longer and operate more reliably.
Provide effective protection from vibration to the receiver, battery, servos
and other RC and electronic components. Observe the advice included in
the relevant operating instructions. Balance propellers and rotor blades
before use and replace them at any sign of damage. Install I.C. engines
on vibration-absorbing mounts and replace motors or motor parts which
are damaged or do not run true.
Do not strain or bend cables; protect them against rotating parts.
Avoid unnecessarily long or superfluous servo extension cables.
Safety instructions
PROFI TX
Use cables with sufficient cross-section.
Do not coil up or shorten the receiver aerial. Do not lay the aerial on or close
to electrically conductive components. Deploy aerials outside of fuselages
with a shielding effect (carbon fibre, metallic painted finish).
Observe also the advice included in the relevant receiver operating instructions!
Ensure that the receiver power supply is of adequate capacity. For servos up
to about 40 Ncm torque you can estimate the required battery capacity using
the following formula:
Capacity [mAh] ≥ servo count x 200 mAh.
Use the next larger size of battery!
Take care to maintain sufficient distance between cables carrying heavy
currents (e.g. electric power system) and the RC system. Especially the
cables between brushless electric motors and their actuators must be kept
as short as possible (guide value: max. 10 to 15 cm).
Check the model regularly
Free movement and zero backlash of rudders and linkages.
Stability and flawless condition of rods, linkages, hinge joints, etc.
Carry out a visual check for fractures, cracks, possible shear points etc. on
the model itself, and in its components such as the RC and power systems.
Flawless condition and contact stability of cables and plug connections.
Absolutely essential: Examine the power supply and its wiring, including the
switch harness, and the external condition of the battery.
This entails regular maintenance of the battery and periodic checks of the
voltage curve and capacity, employing a charge process and battery charger
suitable for the type of battery in use.
Safety instructions
PROFI TX
Page 19
Pre-flight checks
Charge the transmitter, receiver and flight batteries carefully, and verify their
state of charge at regular intervals.
Ensure that the correct model memory is active.
Carry out a range check (see section 3.6 "Range check" on page 47).
Check the function and effect of all primary and secondary control systems.
If you discover any irregularities, do not fly. Locate the problem, eliminate it, and
then check again.
When operating the model:
If you have never flown a radio-controlled model before, it is highly
recommended you consult an experienced model pilot when getting started.
A trainer (buddy-box) system is ideal for taking the first steps in learning to fly.

2.5 Liability and indemnification
The model sport with radio-controlled models is a fascinating hobby. However,
model aeroplanes, vehicles and ships are not toys. Their assembly and operation
require a high level of technical knowledge, careful craftsmanship, safety-
awareness and responsibility. Errors, inattentiveness or even negligence can
lead to considerable damage to property or severe personal injury. Generally, you
as operator are responsible for any threat arising from your model. This absolute
liability will not be assumed by the manufacturer. This is also applicable in the
event of uncontrollable external influences and interferences. You are expected
to exercise extreme care as operator of a model.
Since manufacturers or dealers cannot have any influence on proper setting up,
maintenance and operation of the model and the radio control system, such risks
are expressly pointed out here.

3.4 Transmitter battery
The PROFI TX is powered by a very robust and durable LiFePO4 battery.
The battery is installed with the electronic system for battery management in a
welded case. If the battery is new, the battery capacity of 4000mAh provides an
uptime of more than 25 hours. Additionally installed components increase power
consumption and shorten the operating time. If the device is exposed to very low
temperatures, the operating time is significantly reduced.
3.4.1 Charging the battery
The PROFI TX features two USB sockets at the front on the right-hand side of the
case, which are protected by a sliding latch. The mini USB socket is used for
charging (see section 3.1.5 "Connections" on page 29).
The following options are available for charging the PROFI TX:
Via your PC or laptop
Via the MULTIPLEX USB car plug-in charger 12V DC
(item no. 145533)
Via the MULTIPLEX USB plug-in charger 100-240V AC
(item no. 145534, see section 10.2, "Accessories" on page 213)
The trans mitter must not be connected to a charger when no battery is installed!
Without a consumer, the charger can provide unacceptably high output voltages.
These voltages can damage the transmitter.

3.4.4 Battery management
The PROFI TX records the current during transmitter operation and while loading
the transmitter battery. The available battery charge is calculated on the basis of
the power meter reading, the temperature and the voltage. The remaining
operating time (time to empty) is calculated from charge and current and is shown
on status display #2 (see page 87). The calculation takes into account that current
consumption slightly decreases with decreasing battery voltage.
Battery alarm
If the remaining operating time (time to empty) falls below the set threshold,
an audible alarm is issued. The respective displays flash on status display #2.
The factory setting for the alarm threshold is 60 minutes. This value can be
changed in the Setup > Transmitter > Battery alarm menu (see section
5.3.8 "Transmitter" on page 109).
Self-discharge
If the transmitter is stored for a prolonged period, the available battery charge is
calculated on the basis of multiple parameters when the transmitter is switched on.
The displayed charge and time to empty are not initially very accurate. Precise
values are displayed after a few charging / discharging cycles.
Under-voltage cut-off
If the operating voltage falls below 2.8V the device is automatically switched off
without further warning. If the voltage is below 2.9V, it cannot be switched on:
The following message is briefly displayed on the screen: BATTERY DOWN!
Charge the transmitter battery!
If voltage is low, recharge batteries as soon as possible (within 1-2 days) to avoid
damage due to total discharge. Observe the notes on charging (see section 3.4
"Transmitter battery" on page 41).

4. In the Servo > Test run menu, activate the test run for a control function,
e.g. Elevator. This allows you to check that the receiving system responds to
control commands with distinct, regular movements of the control surfaces.
5. Increase the distance between transmitter and model. You have reached the
range limit when the servos start to jitter.
6. Repeat the check with the power system running. Secure the model. Perform the
check using throttle positions that vary between idle and full throttle. In case of
electric power systems, the most significant interferences occur at half throttle.
The range should not diminish significantly.
7. Otherwise, eliminate the cause of the interference (engine or motor, installed
position of the receive system, power supply).
Factors influencing the radio range
The following factors have significant influence on the radio range:
Environmental conditions
Hilltops, ground characteristics, type of terrain, and the atmospheric
conditions affect radio range.
Receiver technology and sophistication
Technically sophisticated receivers have greater range than simple, cheap
receivers.
Radio installation in the model
Installation position / arrangement of the aerials and the distance to
batteries, power systems, servos, ignition systems, metal / carbon fibre parts
influence the radio range.
Binding
The binding procedure binds the receiver with the transmitter.
M-LINK uses "frequency hopping" and "spread spectrum".
No fixed transmission channel is used for "frequency hopping", but all 39 channels
are used in a sequence that is defined by the transmitter.
Transmitter
PROFI TX
Page 49
For "spread spectrum", every data bit is coded in 64 bits (spread). This procedure
provides a high level of interference resistance. During binding, the transmitter
passes "hopping sequence“, "spreading code", and "response time" to the receiver.
Procedure
1. Press and hold the tool button and switch the transmitter on. Once activated,
the safety check display is shown. Follow the instructions shown.
o The (flashing) message "BINDING" is shown in the status displays #2 to #8.
o The annular light of the Power button is flashing in orange.
2. Switch on the receiver by pressing and holding the SET button (connect the
power supply).
The receiver LED is flashing rapidly.
The binding procedure is completed within a few seconds:
o The annular light returns to flashing yellow.
o The receiver LED is flashing slowly.
o The servos that are connected to the receiver can now be controlled.
If the binding procedure does not automatically complete within a few seconds,
move the transmitter front closer to the receiver aerial(s).

3.7 Trainer mode
The trainer mode (teacher / student) is the safest method for beginners to get
started in model sport.
An experienced model pilot has control over the model as the teacher. The trainer
can transfer control functions to the student by operating a button. Initially these will
be individual control functions, and later all the main control functions.
The PROFI TX can be configured either as a teacher transmitter or as a student
transmitter. The teacher and student transmitters are inter-connected using a
second M-LINK radio link.
If the radio link between the student and the teacher is interrupted, all the control
functions are returned to the teacher.
Student mode
In Student mode, the control signals of the sticks and sliders are transferred via
M-LINK to the teacher transmitter (without trim and travel settings).
A second PROFI TX with COPILOT module or another MULTIPLEX transmitter
with trainer stick can be used as the teacher transmitter.
Refer to "Training" on page 96 for details.
Teacher mode
A free switch on the teacher transmitter and the COPILOT module are required for
the Teacher mode (see section 10.2 "Accessories" on page 213):
Refer to section 3.3.4 "Installing additional controls" on page 37 for
installation instructions.
The assignment of the switch to the trainer function is described in section
6.4.2 "Assigning switches" on page 171.
Refer to section 3.3.5 "Installing additional modules" on page 40 for
information on how to install the COPILOT module.
In Teacher mode, the selected control functions can be controlled by the student
transmitter. These control functions are selected in the Setup > Training menu.
The selection list is only available in Teacher mode.

3.8 Digital trim
3.8.1 Overview
"Trimming" refers to the adjustment of the model aircraft to fly straight and level
when you leave the sticks exactly at centre.
Digital trim has two essential advantages:
The physical position of a conventional trim with trim slider corresponds to the
actual trim value, while digital trim buttons do not. The digital trim position is
displayed on the screen, and any change to the trim values is stored in the
model memory. If you switch model memories, there is no need to move the
trim sliders to the correct position to suit the model. The correct trims are
immediately available.
In models for which you have set up multiple flight phases each flight phase
has its own trim memory, i.e. it is simple to trim each flight phase accurately,
and independently of the trims in the other phases.
Example
The model aircraft should fly straight and level when you leave the sticks exactly at
centre. If this is not the case, the neutral point of the causal control function should
be corrected / trimmed.
Centre trim
The PROFI TX enables digital trim on each of the four stick axes.
"Centre trim" (the centre trim principle) is applied to the main control functions
"Aileron", "Elevator", and "Rudder". The trim only affects the control centre, but not
the end-points. Unlike standard trim, this offers the advantage that no control travel
must be reserved for trimming: the servo travel is used fully.
Both servo end-points remain unchanged, regardless of the current trim position.
3.8.2 Trim buttons
In the case of the PROFI TX, trimming is carried out using the buttons arranged
below and to the side of each stick unit (see section 3.1.1 "Top view" on page 23).
They are located in an ergonomically efficient position, and are easily reached
when using the transmitter, whether hand-held or in a tray.
The effect of each button-press is to shift the trim of the associated control axis in
the corresponding direction. If you hold the trim button pressed in for longer than
Transmitter
PROFI TX
about 0.8 sec., the trim value changes continuously until you release the button
again (AUTO-REPEAT function). When the trim reaches centre, the AUTO-
REPEAT function stops briefly.
Each trim increment is accompanied by an acoustic signal. On reaching the trim
centre and on reaching the maximum trim range, specific acoustic signals are
emitted to alert the user. The volume of the acoustic signals during trimming can
be configured in the Setup > Transmitter > Volume menu (see section 5.3.8
"Transmitter" on page 109).
3.8.3 On-screen trim display
Graphic display
The trim positions are displayed as bars at both sides and at the bottom of the
screen in the status displays #2 to #8:
Fig. 7: On-screen trim display
Starting from the trim centre position, the trim range is 20 increments in both
directions. The trim increment (step, or adjustment rate) can be set to any of four
values (0.5%, 1.5%, 2.5%, 3.5%) (ControlFunctions > respective control
function, Step size parameter, see section 5.4 "ControlFunctions main menu"
on page 112).
Switching the step size changes the trim value percentage since the number of
stored trim increments remains the same. This means if you alter the trim increment
size, you must remember to re-trim the model.
The design of the graphic trim display can be selected (Setup > Transmitter >
Display, Trim graph parameter, see section 5.3.8 "Transmitter" on page 109).

Switch assignment
In the PROFI TX, all the switches can be installed and connected as needed. For
this reason, switched functions that are usually assigned to dip-switches or buttons
cannot be pre-set in the model templates. You have to configure these
assignments yourself according to the existing switches.
Using timers
The Frame, Sum, and Interval timers are only functional if a switch has been
assigned to them. The same control used for the Throttle control function is
assigned to the sum timer in all model templates. For this reason, this timer is
immediately functional. You activate the other timers by assigning a switch to them.
Control mixers (Ctrl.Mix)
The control mixers Ctrl.Mix are not initialised in the templates.

4.1.1 BASIC model template
This model template is designed for simple power or glider-type models and for
models without aileron. On account of its simplicity this model template is ideally
suited to model flying simulators.
Servo assignment
If you install a second aileron servo to provide separate linkage for the ailerons,
simply assign the Aileron function to a free servo (see "Assignment" starting
from page 142). Would you like to raise the ailerons as an airbrake? In that case,
assign the AILERONS+ mixer to both aileron servos at the same position. In the
extended state, the airbrake will cause major load distribution changes: Change
the elevator to ELEVATOR+. It is then possible to compensate for the effects of
Throttle and Spoiler (airbrake).
Pre-defined mixers on the control side, with 2 more that can be defined by
the operator.

In the basic configuration, this model template is optimised for helicopters with
flybarless controller. The classic configuration can easily be restored by assigning
tail rotor mixers and main rotor mixers on the servo side.
The template is equally suited to collective pitch-controlled electric helicopters with
mechanical main rotor mixer. The "Governor mode" option is activated for Throttle.
Switch off this option if you prefer to work with throttle curves (see "Throttle
(helicopter)", page 118).

4.3.3 TRACKED V. model template
This model template is suitable for tracked vehicles.
Control function assignments and names can be changed as required.
Completed tracked vehicle models typically contain a functional building block that
combines "Throttle" and "Steering" for the two power systems.
If you are using 2 separate speed controllers, it is recommended to change the
servo assignment for Steering and Throttle to TRACK+ (page 142).
TRACK+ stands for a mixer that combines "Throttle" and "Steering". You configure
the required settings in the £ Mixer menu (page 126).
Set a small deadband value in the mixer for Steering. If "Steering" and "Throttle"
are assigned to the same stick unit, opening the throttle often involves a small
steering movement. Applying a deadband to "Steering" solves this problem.
To personalise control, 4 mixers on the control side and 6 mixers on the servo side
are provided, each with eight outputs.

The status display is shown after transmitter start-up or when exiting the main
menus.
Press the + or – buttons or use the central wheel to toggle between screens. Every
clockwise increment on the central wheel cycles to the next status display (see also
chapter 6 "Operating the transmitter" on page 160).
5.1.1 Status display #1
Status display #1 provides an overview of the current battery and device status:
The device name is shown in the first line. You can overwrite this name with
customised text (menu: Setup > Transmitter > User data > Name
parameter, see section 5.3.8 "Transmitter" on page 109).
The left side of the table provides information about the battery, e.g. battery
voltage, remaining operating time (time to empty), etc.
The right side of the table provides information about the device, e.g. serial

5.2 Menu structure
The PROFI TX menus are structured in several levels:
Main menus
The 6 main menus are opened via the 6 direct menu access buttons (see
section 6.1.1 "Direct access buttons for menus" on page 160).
The main menus only provide links leading to the menus themselves.
Each link is always indicated by a succeeding series of four full stops.
Menus
The menus can contain both links to sub-menus and parameters.
Sub-menus
The sub-menus only contain parameters.
Parameters
Parameters are set values which appear in menus and sub-menus. Some only
provide information, but others can be edited.
Uneditable parameters are skipped when browsing.
Navigation in the menus
You can use the buttons or the central wheel to navigate through the menus:
1. Press one of the direct access buttons to open the respective main menu.
2. Use the central wheel or press the + or – buttons to select a menu item.
3. Press the wheel or the ENTER button to access the respective sub-menu.
4. Press the wheel or the ENTER button to move to an input field.
Refer to chapter 6 "Operating the transmitter" on page 160 for detailed information
on how to navigate in menus and enter values.
A ▼ or ▲ arrow on the left edge indicates that the menu contains more lines than
can be displayed on screen.
Continue to browse using the central wheel or the + / – buttons to scroll to the top or

The radio link functions are set in the M-LINK menu.
Range check
When performing a range check, the transmitting power is significantly
reduced to allow shorter distances between transmitter and model (see section
3.6 "Range check" on page 47).
Set Failsafe
The current servo positions are stored in the receiver.
If Failsafe positions were stored in the receiver the servos return to these
positions after 0.5 seconds.
o Use the respective PROFI TX controls to move the servos
(surfaces) of your model to the desired positions.
o Set the value to ON. After a few moments, it reverts to OFF.
o Check the Failsafe function by switching the transmitter off.
FastResponse
FastResponse reduces the transmission cycle from 21 ms to 14 ms. This
reduces the response time for control commands. Only 12 servos can be
controlled when FastResponse is active.
Not all servos work properly with FastResponse. Incompatible servos may vibrate
excessively in idle position. Check your servo before starting off on the first flight.
FastResponse has a noticeable effect only on extremely agile models that are
equipped with fast servos.

5.3.2 Flight phases
It is useful to have different settings and trims for specific flight phases when flying
models. The flight phases technology in the PROFI TX provides an easy and
convenient way to realize this. You can copy settings for one flight phase to another,
lock flight phases if they are not needed, assign switches to flight phases, etc.
Refer to section 8.2.10 "Working with flight phases" on page 207 for information on
how to work with flight phases, assign switches to flight phases, lock / unlock flight
phases, etc.
Flight phase number (1, 2, 3, or 4)
Identifies the flight phase in other menus. In the control function menus,
all settings that can differ between flight phases are accompanied by the
respective identifying number 1 to 4 for the flight phase.
Menus
PROFI TX
Page 95
Flight phase name (e.g. SPEED1)
You can select the designations for the flight phases from a list of 13 pre-set
names (see section 8.2.10.5 "Changing flight phase names" on page 210).
After activating the input field for the name, select a suitable name by pressing
the + / – buttons or by using the central wheel.
Locked flight phases are shown crossed out.
x
Identifies the active flight phase.
Switch (e.g. 1>)
Switch that is assigned to the flight phase; the arrow indicates if the left (<) or
right (>) switch is associated.
Three dashes "---" indicate that no switch has been assigned for switching
between flight phases.
Slow
Transition time to the next flight phase.
Switching flight phases may involve major surface position changes. Sudden
major changes e.g. to camber-changing flaps or airbrakes make controlling the
model difficult and lead to undesired, hard transitions to the next flight phase.
These problems do not occur when the transition is performed slowly. The
transition is automatically calculated in such a way that all servos move to their
new positions in a synchronized manner and within the selected time frame.
The control commands by the pilot are not slowed down.
Possible range: 0.1 to 6.0 seconds
Pressing REV/CLR
Locks or unlocks the selected flight phase.
Menus
PROFI TX
5.3.3 Training (principle)
In trainer mode (teacher / student), a wireless connection is established between
two Multiplex transmitters via M-LINK.
The teacher transmitter controls the model and must be bound to the model
(Binding). The student transmitter transfers the stick signal to the teacher
transmitter via M-LINK. The teacher can transfer a freely definable group of control
signals to the student.
The teacher transmitter requires a receiving device for the student signal. On older
transmitters with DIN socket, the trainer stick is the receiving device; the PROFI TX
uses the COPILOT module.
The trainer stick or the COPILOT module are bound in the same way to the student
transmitter (Binding) as receivers.
5.3.3.1 Student mode
Set Training to ON. This activates the training system.
Set "Format" to MPX if the teacher uses an older Multiplex transmitter that
does not support the UNI format.
Set Mode to Student.
Now, the student transmitter must be bound to the receiving device of the
teacher transmitter. For this, "Binding" must be activated on both sides.
o Activate "Binding": The display changes to seeking...
o Now, activate "Binding" on the receiving device of the teacher
transmitter. Place the front of the PROFI TX close to the receiving
device of the teacher transmitter.
o After a few moments, the "Binding" display changes from
seeking.. to Teacher.
This indicates that the radio link to the receiving device of the teacher transmitter
has been established.
Menus
PROFI TX
Page 97
The message STUDENT MODE flashes on the status displays #2 to #8 while the
Student mode is active.
Both transmitters must use the same Format setting; otherwise, the centre positions
of the control signals will differ.
Remember to set "Training" to OFF if you wish to control the model directly.
5.3.3.2 Teacher mode
For Teacher mode, a COPILOT module and an assigned switch are required (see
section 3.7 "Trainer mode" on page 50).
Set "Training" to ON. This activates the training system. In Teacher mode,
the COPILOT module is switched on. This increases the power
consumption by 30 mA.
Choose the same servo format setting as on the student transmitter.
Otherwise, the neutral positions of the servos will not match.
Set the Mode menu item to Teacher. This switches the COPILOT module
on. The power consumption increases by 40 mA. Now, 7 control functions
are displayed below, which can be transferred to the student individually or
in groups.
Activate "Binding" on the student transmitter.
Open the "Binding" menu item and turn the wheel by one clockwise
increment. The display changes from OFF to seeking.. The COPILOT
module is now bound to the student transmitter. After a few seconds, the
display should change from seeking.. via OFF to Student. If this is not
the case, hold the PROFI TX over the aerial of the student transmitter (the
COPILOT is positioned below).
The following elevator example illustrates how control functions are
assigned to the student.
o Open the "Elevator" menu item.
o Operate the elevator stick on the student transmitter vigorously.
Menus
PROFI TX
o The servo channel used by the student transmitter for transmitting
the elevator signal is displayed next to Elevator, usually Ch2.
o Check on the model if the rotation direction of the student signal is
correct. You can reverse the direction by pressing the REV/CLR
button.
Make sure that the model motor cannot start up!
o Close the menu item.
Repeat these steps to assign all control functions that the student is
allowed to control.
If the teacher switch is switched on and the connection to the student
transmitter is established, the student controls the assigned control
functions.
Important information:
If the control functions are transferred to the student, the message
STUDENT CONTROLS flashes on the status displays #2 to #8.
If the connection to the student transmitter is lost, all control functions
are returned to the teacher.
Binding can be switched off by rotating the wheel to the left while the
menu item is open.
Turn OFF the training system after completing the training. Otherwise, the student
may inadvertently re-establish the student connection by switching on the
transmitter and take control of your model.
Besides, the power consumption of the COPILOT module reduces the operating time.

Overview
5.3.4.1 Variometer
Sink rate
Sink rate of your model.
Possible range: -0.1 m/s to -2.0 m/s
How the variometer tones change from climbing to descending is adjusted
accordingly:
Climbing
High tone; pitch and interval frequency increase proportionally with the climb rate.
Descending
Low tone (hum);
o From "0 m/s" to "Sink rate": pitch and interval frequency are
proportional to the climb rate.
o Below sink rate: continuous low tone without interval.
o From "-3 m/s": no tone.

5.3.7 Define mixer
You can use the Define mixer menu to define how the mixers on the servo side
are construed. The parameters are configured in the Mixer menu (see section 5.5
"Mixer main menu" on page 126).
The mixer definition determines the structural design of the mixer. Each mixer can
combine up to eight control functions (mixer inputs). A switch can be assigned to
every input. The mixer method is defined using options.
The number of mixers depends on the model template selected. Helicopters have
2 of these mixers, all other models have 7. Depending on the template, several
mixers are pre-defined and have descriptive names. These names are used to
assign the mixer outputs to the servos.
Each mixer has the following sub-menu:
5.3.7.1 Name
The Name parameter shows the name of the mixer.
You can enter a new name or edit the name as desired (see section 6.1.3 "Text
input" on page 162).
5.3.7.2 Mixer inputs
The name of the mixer is followed by eight numbered lines with three input fields each.
Menus
PROFI TX
Control function
You select the mixer input in the first field simply by operating the desired control
function. Naturally, this only works if the control (actuator) has a control function
assigned. Alternatively, you can use the + / – buttons or the central wheel to select
a control function as mixer input.
Switch
In the second field the mixer input can be configured as switchable. To do this,
simply operate the desired switch. Upon exiting the input field the switch position is
ON. The arrow next to the switch name points in the direction of the ON position
(' or #). When the switch is switched on an asterisk "*" appears next to the arrow.
Alternatively, you can assign the switch using the + / – buttons or the central wheel.
The switch can be reversed by pressing the REV/CLR button.

The menu is dynamic:
It lists only the control functions that are actually used, i.e. the control function
must control at least one servo—either directly or indirectly using mixers.
The menu content differs for vehicle models, fixed-wing models, and
helicopter models.
Control functions that do not have configurable parameters are not shown
(Wheel Brake, Mixture, Towing dog).

o Values that can be assigned to a digi-adjuster are marked by
a horizontal dash preceding the input field (see section 6.3.1
"Allocating a set value" on page 164).
o The number next to the parameter name identifies the flight phase
(in the example: 1) to which this value applies (see section 5.3.2

5.4.1 Aileron, Elevator, Rudder
The following control functions operate identically:
Aileron, Elevator, and Rudder for fixed-wing models
Aileron, Elevator, and Rudder for helicopter models
Trim
Current trim setting of the control in the respective flight phase (only display).
Step size
Trim increment: 0.5%, 1.5%, 2.5%, 3.5%
Step size defines the trim change (in %) per trim increment (see section 3.8
"Digital trim" on page 51).
For general-purpose use an increment size of 1.5% has proved a good compromise.
For very fast models with accurate control surface linkages or models with very
large control surface travels (e.g. FunFlyers) a trim increment size of 1.5% could be
too large. In this case, the Step size can be set to 0.5% providing very fine trim
control.
D/R
Dual rate: 10% to 100%
The dual rate setting is used to change the control sensitivity of the control.
If the D/R for a control function (e.g. Aileron) is set to 50% you can use the
assigned switch to reduce the control surface travels on the model by half for
finer control. The control curve in the graph changes accordingly when you
operate the switch assigned to D/R.
Menus
PROFI TX
Travel
Setting for the control travel (flight phase specific): 0% to 100%
You can influence the control sensitivity of a control during a specific flight
phase using the Travel parameter. That means you can configure a different
value for each flight phase, e.g. in the flight phase NORMAL = 100% for
maximum control surface effectiveness, in the flight phase SPEED1 = 60% for
finer control.
Make sure to activate the desired flight phase first before making any changes!
Expo
Flight phase specific: -100% to +100%
The Expo parameter can be used to assign an exponential characteristic to a
control curve.
o For Expo = 0%, the control works in a linear fashion.
o The effect of negative Expo values is that the control generates
smaller control surface travels around the centre position providing
finer control.
o The effect of positive Expo values is that control surface travels
are increased around the centre position.
o The end-travels remain unchanged when Expo is used. So, full
travel is still available when required.

(speed controller).
OFF The throttle curve is used. Individual curves are used for each
flight phase.
ON A controller with active Governor mode is used: Each flight phase has
a fixed value.
Governor OFF
P1 to P7
7-point curve, flight phase specific:
0.0% to 100.0% (= full throttle) for all points on the curve P1 to P7.
Resolution: 0.5%.

Lower limit
Defines the lower limit for the throttle curve to ensure safe idle speed.
This setting is overridden in the auto-rotation flight phase (AUTOROT).
Not required for models with electric power system: Thus, set to 0%. The flight
phase-dependent throttle trim is added to the lower limit and thus increases
the lower limit by the trim value.
The horizontal dotted line in the graph shows the position of the throttle limiter
in all flight phases.
Run-up Time
Slow function for throttle: 0.0s to 6.0s
This parameter defines the time for running up from idle to full throttle. This
does not affect the run-down time.
5.4.3.1 Throttle curves (Governor OFF)
For each of the flight phases 1 to 4 a separate throttle curve with 7 points can be
configured to achieve optimum adaptation of the motor power to the throttle curve
setting for the respective flight phase.
The aim is to achieve a constant system speed over the entire collective pitch
range. Ultimate fine-tuning of the throttle curve is only possible in flight and
depends on many parameters (motor power, motor setting, power characteristics,
setting for the collective pitch curve, rotor blades used, etc.). If a parameter is
changed fine-tuning of the throttle curve must usually be repeated.
Tip: Switch a digi-adjuster to the curve point to be configured. Refer to page 164 in
chapter "Digi-adjuster" for details.
To assist configuration the current position of the collective pitch stick is displayed
in the graph as a vertical dotted line.
Menus
PROFI TX
Special case: auto-rotation
In the AUTOROT flight phase the throttle curve is switched off. All curve points have
the same value: You can set the throttle position for auto-rotation at every curve
point. The lower limit is switched off. For training with an internal-combustion
engine, set a value at which the motor does not yet stop.
Example: throttle curve in the HOVER flight phase
Simple throttle curve for hovering:
For a negative collective pitch (= descending) the lowest motor power is
required (in the example: P1 = 35%).
A positive collective pitch (= climbing) requires the highest motor power
(in the example: P7 = 85.5%).
Example: throttle curve in the 3D flight phase

and inverted flight:

Governor ON for electric helicopters with brushles s motors in Governor mode
In Governor mode, the speed controller (governor) provides for a constant system
speed. It merely requires a fixed value for the required system speed in the
respective flight phase. The throttle curve can be switched off in the
ControlFunctions > Throttle menu by choosing the setting Governor = ON.
5.4.4 Spoiler, Flap, Retract.Gear, Speed, Aux-1 to Aux-4
The following control functions operate identically:
Spoiler, Flap, Retract.Gear, and Aux-1 to Aux-4 for fixed-wing models
Spoiler, Speed, Retract.Gear, and Aux-1 to Aux-4 for helicopter models
Slow
Slow function: 0.0s to 6.0s
You can use this parameter to reduce the actuation time for the control function;
i.e. the connected servos travel from one end to the other during this time.
Fixed value
Flight phase specific: -100%.. 0, OFF, 0.. +100%
Allows setting a control function to fixed positions that are dependent on the
flight phase. If OFF is selected the function is controlled by the assigned control,
provided an assignment exists. If this is not the case, refer to page 101.
Example of the Flap control function
Objective: Fixed, optimised flap position (camber) in specific flight phases.
You use 3 flight phases: SPEED1, NORMAL, THERMAL1.
Preparation: Use the GLIDER+ model template. A 3-position switch must
be assigned to the phases 1-3 for switching between the flight phases
(see page 104).
Menus
PROFI TX
Open the Controls > Flap menu item. To begin with, set estimated values
for the Fixed value of the flight phases SPEED1 and THERMAL1. Retain the
value OFF for the NORMAL flight phase. Allocate a digi-adjuster (see page 164).
The allocation applies to all flight phases.
Now, you can use the digi-adjuster to optimise the camber in flight from the
status display. If OFF is selected, the digi-adjuster has no effect: The flaps are
controlled by the assigned control. When the optimum camber has been
identified allocation of the digi-adjuster can be erased (see page 166).
5.4.5 Gyro
This control function is used to control the sensitivity of a gyro. You can select a
different sensitivity setting for each flight phase. Alternatively, you can control the
sensitivity using a control (actuator). To this end, simply set the sensitivity to OFF
and assign a control to the Gyro control function in the Setup > Assign.Controls
menu.
Select the gyro model used in Type of Gyro. If your gyro is heading-hold
capable, the gyro type Heading must be selected even if you only use the
damping function.
The following table lists the characteristics and differences between the two gyro
systems:
Damping gyro
Heading-lock gyro
This gyro type dampens the rotational
movement of a model around the axis to
which the stabilisation is applied.
To maintain good control of this axis the
damping effect should be reduced
proportionally with stick travel. The
reduction level is configured by
selecting a setting between 0 and 200%
for the Suppression parameter.
The servo pulse of the gyro channel
This gyro type supports two operating
modes: "Damping" and "Heading". You
can switch between the modes by
changing the prefix for the sensitivity
setting.
The gyro operates in Damping mode (as
described in the opposite column) if the
sensitivity setting is a positive value.
In Heading-lock mode the control signal
for the axis to be stabilised is used as

the setting for the rotational speed
around this axis. In neutral position the
rotational speed is maintained at zero:
The model always points in the same
direction.
The sensitivity setting ranges from
0% ... 100%:
The sensitivity setting ranges from
-100% ... +100%:
Fixval.Sense
With this parameter, a fixed gyro sensitivity is set for each individual flight phase.
Alternatively, a control can be used. If this is preferred, set the sensitivity to OFF
and assign a control to the Gyro control function. Refer to page 101 for more
details regarding controls assignment.
o The following applies to pure Damping gyros: Adjustment range: 0% to +100%
o The following applies to Heading gyros:
Adjustment range for heading-hold: -100% to -1%
Adjustment range for damping: 0% to +100%
Only the value of the activated flight phase can be displayed. When implementing
changes make sure to activate the desired flight phase first.
The next line indicates if a heading gyro operates in Damping or Heading mode.
If the sensitivity parameter is set to OFF and a control is assigned to the "Gyro"
control function, the value supplied by this control and the respective identifier (<E)
are displayed next to it on the right. If no control is assigned, nothing is displayed
and the sensitivity setting is zero.
Menus
PROFI TX
Suppression
In Damping mode, the gyro also counteracts intentional control commands.
For improved control, the gyro sensitivity can be suppressed proportionally to
stick travel using this parameter. This function is already integrated in many
gyros. In this case, retain the value OFF.
Adjustment range: OFF to 200%
The setting 200% reduces damping to 0% at half stick travel. If the gyro has its
own suppression function, set the value to OFF.
Controlled axis
Here, you select the control function on which the gyro takes effect in the model.
In Heading-hold mode, the trim for this control function is switched off. For
helicopters, the static tail rotor compensation using the TAIL ROTOR mixer is
also switched off.
In Damping mode, the selected control function is used to reduce the level of
damping (suppression).
If you are using a Heading-hold gyro, you must check whether the gyro operates in
the displayed mode before operating the model. Make sure that the model motor
cannot start up. Then, switch on the receive system and the gyro.
Set the sensitivity to a mid-range negative value: "Heading" is now displayed
for mode.
Hold the rudder or tail rotor stick in an end position.
If the rudder or tail rotor moves to an end-point, the gyro operates correctly in
Heading-hold mode.
If this is not the case, the gyro operates in Damping mode: The rotation direction of
the Gyro servo channel must be reversed! The respective procedure is described on
page 139.

The +SPOILER mode should be selected if the ailerons are
raised to use them as additional landing aid.
This suppresses the differential when operating the landing
aid (Spoiler control function). As a result, the aileron travels
are not reduced in the downward direction, enhancing aileron
response during landing.
Differnt.Ail
Flight phase specific setting for the differential level.
If the differential is incorrect (aileron travel is reduced in upward direction
instead of downward), reverse the value (REV/CLR button).
5.5.1.3 Ctrl.Mix
Two control mixers are provided for fixed-wing models. They mix the signal of any
second (Source) control function into any (Target) control function. The mixer

5.5.1.4 Mixers on the servo side
"Mixers on the servo side" combine up to 8 control functions in one common output
signal. You can assign a unique name to each mixer. It is possible to assign the
output signal to one or more servos using the name of the mixer.
For safety reasons, the mixers are defined and configured in separate main menus.
In this menu, only the travels and other parameters are configured. Only mixers are
shown that are actually used, i.e. that are assigned to a servo.
The mixers are defined in the Setup > Define mixer menu (see section 5.3.7
"Define mixer" on page 105).
The following example of the AILERONS+ mixer, which is used in the GLIDER+
model template, illustrates how mixers on the servo side are configured.
Each line on the screen has 2 input and 2 display fields:
Aileron: The aileron travel in an upward direction is set here. The differential is
set using A.-Differential. Observe the directions of stick and rudder: Reverse
the travel using the REV/CLR button, if required. In addition, check the differential
direction. Level and direction can be adapted for all aileron inputs using the A.-
Differential mixer. If "Spoiler" is mixed in, you should switch the differential
mode to +SPOILER.
Spoiler: The end-travel of the spoiler on the aileron is configured in addition to
full travel. The direction is determined by the prefix of the set value.
Apply an offset (offs) to shift the zero point of the output signal to make full use of
the servo travel (always in opposite direction of the spoiler).
Flap: Configure the rudder travels separately for up and down using the two set
values.
Elevator: The input is used untrimmed. Configure the rudder travels separately for
up and down using the two set values. Usually, this mixer should be switchable. As
we do not know the type and location of the switches installed in your transmitter it is
not possible to assign switches in the templates. However, you can assign switches
in the Setup > Define mixer menu (see section 5.3.7 "Define mixer" on page 105).

5.5.2 Helicopter models
Overview
The 4 Ctrl.Mix mixers are always shown.
The other mixers are only displayed if at least one servo is assigned.
In the model templates HELImech., HELIccpm, and eHeli FBL, the TAIL
ROTOR mixer is assigned to a rotor and is, therefore, shown here.
Servos are assigned to the main rotor mixers in the HELIccpm template;
as a result, MAINROTOR is displayed here.
The MAINROTOR mixer is shown if it is assigned to one of the servos
MAINROTOR-R., MAINROTOR-L., MAINROTOR-F, or MAINROTOR-B.
If you remove the TAIL ROTOR and/or the MAINROTOR mixer from the
servo assignment, the corresponding mixers also disappear from the menu.
5.5.2.1 TAIL ROTOR
Mixer for the tail rotor. Refer to section 8.2.6 "Checking and adjusting the tail rotor"
on page 201 for information on how to check and adjust the tail rotor and for a
detailed description of the workflow for the TAIL ROTOR mixer.
Preparations
To display the TAIL ROTOR mixer in the Mixer menu the TAIL ROTOR must
be assigned in the Servo > Assign menu (see section 5.6.2 "Assignment"
on page 142).
Menus
PROFI TX
A 2-point calibration is sufficient for TAIL ROTOR. Take care that the servo is
not stalled (mechanically obstructed) at its end-points (P1, P5)!
All settings for throttle and collective pitch must be completed before the TAIL
ROTOR mixer is configured. Subsequent changes usually require a correction.
The TAIL ROTOR mixer is only activated in the Damping mode of the gyro. In
Heading mode, it is switched off (see section 5.4.5 "Gyro" on page 122). If you do
not use Damping mode, you can replace the mixer with the RUDDER control function
(Servo > Assign main menu, see section 5.6.2 "Assignment" on page 142).
Coll.+ / Coll.-
Separate configuration of the collective pitch mixers for the tail rotor when
climbing and descending:
o Coll.+: correction for climbing
o Coll.-: correction for descending
The exact values can only be established through a programme of flight
testing, and vary according to many parameters.
Rudd.Diff.
Reduce tail rotor travel in one direction.
Offset
Pitch angle (offset) for the tail rotor to compensate for the torque at 0º
collective pitch (main rotor).
Zero point
The origin for the static tail rotor compensation mixer.
Starting from this collective pitch setting angle in the direction of "climbing",
the "Collective -> Tail rotor" mixer is added using the value set for Coll.+.
The value set for Coll.- is applied in the other direction (descending).

5.5.2.2 MAINROTOR
You control the main rotor of your helicopter model with the MAINROTOR mixer. The
PROFI TX features a universal swashplate mixer (CCPM) which can be used to
control all types of swashplate fitted with three or four linkage points / servos.
Refer to section 8.2.5 "Checking and adjusting the main rotor" on page 197 for
information on how to check and adjust the main rotor and for a detailed
description of the workflow for the MAINROTOR mixer.
To ensure that the swashplate moves in the required manner, the swashplate servos
must be connected to the receiver in the correct sequence. The channel assignment
varies according to the selected servo assignment and can be viewed at any time in
the Servo > Assign menu (see section 5.6.2 "Assignment" on page 142):

Only required for 3-point swashplates whose linkage points are not equi-
distant from the rotor shaft centre for mechanical reasons.
The difference is set as a percentage (%) of the radial distance (from rotor
shaft centre to the linkage point) between the MAINROTOR-FB and the lateral
MAINROTOR-L. / MAINROTOR-R. servos. The lateral levers are set to 100%.
Adjustment range: -100% - 0° - 100%
Default: 0%
Example
Distance for MAINROTOR-FB: 40 mm
Distance for MAINROTOR-R. / MAINROTOR-L.: 50 mm (= 100%)
The lever for the fore-and-aft linkage (MAINROTOR-FB) is 20% shorter than the
levers for the two side-mounted linkages.
So, you apply the following setting: Lever +/- -20%.
Menus
PROFI TX
TIP
Once you have entered the mechanical values of the swashplate as parameters
for the MAINROTOR mixer, the next step is to carry out a careful and thorough
calibration of the head servos in the Servo > Calibrate menu (see section 5.6.1
"Calibrate" on page 139).
This step is essential to ensure accurate swashplate control. The direction of servo
rotation can be checked using collective pitch control commands. If servos rotate in
the wrong direction, you will need to reverse the rotation direction (REV/CLR button).
It can be useful to disconnect the pushrods between the swashplate and the rotor
head for the servo calibration process, as this makes it easier to calibrate the
maximum travels (P1, P5).
The control travels for Aileron, Elevator, and Collective are then configured in
the ControlFunctions menu (see section 5.4 "ControlFunctions" on page 112).
TIP: Helicopters with Heim mechanics
If you wish to fly a helicopter fitted with the HEIM mechanical system, proceed as
follows:
1. Select the HELIccpm template for the new model.
2. Change the MAINROTOR-FB assignment to Elevator in the Servo > Assign
menu. Now the front/back swashplate servo is controlled directly by the
Elevator.
Set Geometry to 90° in the MAINROTOR mixer. This means that the MAINROTOR-L. /
MAINROTOR-R. servos are only controlled by the Aileron and Collective
functions.
Menus
PROFI TX

5.5.2.3 Ctrl.Mix
These "mixers on the control side" mix the signal of any second (Source) control
function into any (Target) control function. The mixer takes effect on all servos that
are connected to the target control function either directly or via mixer. In helicopters,
these mixers are typically used for throttle compensation. Four of these mixers are
provided in the helicopter templates.
Refer to page 128 for a detailed description of the Ctrl.Mix mixers.
5.5.2.4 Mixers on the servo side
"Mixers on the servo side" are mixers that combine up to 8 control functions in
one common output signal. Their output signals can be assigned to one or more
servos. The mixers are defined in the Setup > Define mixer menu (see section
5.3.7 "Define mixer" on page 105).
If they are assigned to a servo, these mixers can be configured in the Mixer menu
according to the requirements of the particular model.
Refer to page 130 for instructions on how to configure mixers on the servo side.

5.6.1 Calibrate
You can use the Calibrate menu to adjust the travels, centre and any
intermediate points for all servos so that they move evenly and run to the end-
points required.
The menu shows a list of all the servos which can be used with your transmitter
type (9, 12, or 16 servos).
The sub-menu is identical for all servos.
Any parameter changes are immediately reflected in the graph. The channel
number (receiver output) of the selected servo is shown above the graph.
REV/TRM
The REV/TRM parameter has two functions:
o Servo reverse (REV) changes the direction of servo rotation.
To reverse the direction of servo rotation "open" the end-point and
press the REV/CLR button: The entire curve is "reversed" and the
prefixes of all curve points change.
o Servo trim (TRM) shifts all points on the servo curve in parallel. Use
the wheel or the +/- buttons to adjust the trim.
The set trim value results in a parallel shift of the curve. The curve points
are limited to +/- 110%. The shape of the curve remains unchanged until
the limit is reached. The effect is the same as the standard trim
procedure.
Menus
PROFI TX
TRM must only be used for corrections during operation!
Use the TRM servo trim only to compensate for deviations from the neutral position
of a servo that are identified during operation. When configuring a new model it is
better to define the points separately.
P1 to P5
The number of configurable servo calibration points (min. 2, max. 5 points)
varies according to the setting selected when initially assigning the servos
(see section 5.6.2 "Assignment" on page 5.6.2).
You can resolve several issues by making adjustments to the servo calibration
points (parameters P1 … P5):
Establish the maximum working range of the servo:
The servo travels set at this point are never exceeded by the transmitter
(protection from mechanical servo stalling, limit).
Compensate for mechanical differences in the rudder linkage:
For example, adjust the flaps in a multi-flap wing so that they match.
Servo calibration should only be used for fine-tuning. Careful and thorough
mechanical adjustment is strongly recommended.
Never reduce the maximum servo travels (P1 and P5) by more than approx. 30%.
Otherwise, available servo power is wasted, you will forfeit servo resolution and the
play in the servo gearbox will be amplified unnecessarily.
Menus
PROFI TX
Page 141
Procedure
1. Adjust the direction of servo rotation.
o Servos controlled by basic functions (e.g. Aileron, Elevator,
Rudder, ...):
First, check that the rotation direction of the controlled surface correlates
to the control movement. If required, change the rotation direction in the
REV/TRM parameter (REV/CLR button).
If the rotation direction is changed later, you will need to re-calibrate it.
o Servos controlled by mixers (e.g. AILERONS+, DELTA+, V-TAIL+, ...):
In the case of servos to which a mixer has been assigned, the direction of
servo rotation is initially irrelevant. The correct direction can be set later in
the mixer. However, for paired control surfaces—e.g. ailerons with
mixers—the ailerons must rotate in opposite directions. If this is not the
case, one of the servos must be reversed.
2. Select a calibration point (P1 to P5) and open the input field.
3. Press the allocation button for the digi-adjusters.
The servo—and all the other servos to which the same control function or
mixer is assigned—automatically assume the position corresponding to the
percentage figure at the selected calibration point.
With one hand you can easily and conveniently measure and check the control
surface travel (ruler, calliper), while the other hand remains free to change the
value using the wheel.
4. If the travel is correct, press the allocation button F again.
The servo(s) assume(s) the position corresponding to the position of the
associated control.
Vertical line for orientation:
The vertical dotted line in the graph shows the current position of the associated
control for easier orientation. If you activate a value using the allocation button F,
the vertical line jumps to the corresponding point and remains there until you press
the allocation button again or operate the associated control.

6.4 Assigning controls to control functions
The assignment for controls and switches defines which functions in the transmitter
or model are controlled by which control.
Controls, i.e. actuators, are:
Sticks
Slide potentiometers
Rotary potentiometers
Switches and their designated buttons
Controls can be assigned to control functions and/or switched functions. Multiple
assignments are possible and quite useful, e.g. a stick can be assigned to the
"Throttle" control function and also be used as a switch for one or more timers.
Examples of control functions: "Aileron", "Throttle", "Retract.Gear", "Spoiler",
"Flap".
Examples of switched functions: Timer ON/OFF, dual rate, throttle-cut, variometer
tone ON/OFF.
6.4.1 Assigning controls
Controls are assigned in the Setup > Assign.Controls menu. The menu shows
a list of all the controls provided in the software (see section 5.3.5
"Assign.Controls" on page 101).
The basic functions ("Aileron" / "Elevator" / "Rudder" for fixed-wing models and
helicopters plus "Collective" for helicopters only) are always assigned to the sticks.
They are not assigned using the list, but by configuring the controls mode (see
page 169). One vertical axis always remains unassigned and can be assigned
using the list (¢ icon). This is typically used for "Throttle" or "Spoiler" in glider-type
models.
You can use this menu to customise the controls assignment according to your
needs.
Operating the transmitter
PROFI TX
Controls mode
Ailerons, elevators and rudders are controlled by the stick units. The stick units are
assigned to the individual axes using the standardised controls mode (1 to 4).
You configure the controls mode in the Setup > Assign.Controls > Ctrl Mode
menu (see section 5.3.5 "Assign.Controls" on page 101). One vertical axis always
remains unassigned (¢ icon) and can be assigned using the assignment list. In

7.5 Model flying simulator
You can use the PROFI TX to control a model flying simulator in two ways:
Via USB cable
Via M-LINK in conjunction with the MULTIFlight stick
In both cases, you have the following options:
Would you like to work in simulator mode without configuring "Travel",
"Expo" and "Trim"?
Switch ON "Training" in the Setup > Training menu (see page 96).
Select the Student mode. In this case, only unprocessed stick signals are
used for controlling. It is not relevant which model memory is used. Only
the stick assignment must match (see "Ctrl Mode" on page 101).
Would you like to use "Trim", "D/R", "Expo", "Combi-Switch" and "Ctrl.Mix"?
Create a new model using the BASIC template (page 155) and change the
model name (page 157), e.g. to Simulator. Safety check can be
switched off.
From now on, use this model memory for simulator mode.
Would you like to use "Expo", "D/R", "Trim", and "Combi-Switch" for the
simulator?
Create a new model memory based on the BASIC template (page 155).
Change the model name (page 157), e.g. to Simulator.
Alternatively, you can copy the memory of a suitable model. Change the
model name to avoid mix-ups. Do not use the memory of a real-world
model: Settings that you configure for the simulator mode will not
automatically suit your real-world model.
In simulator mode, all the functions on the servo side (mixers, curves, reverse)
are switched off.

8 Creating and customising models
The following chapters contain detailed descriptions of the menus and how the
transmitter is operated using the keypad or central wheel:
"Menus", see page 86
"Operating the transmitter", see page 160
8.1 Fixed-wing models
8.1.1 The procedure in principle
A model memory for a glider is created in this example. The procedure for power
models is identical. The only difference for power models is that Throttle and
Spoiler are interchanged.
The following steps are required to ensure correct operation of the basic model
functions:
1. Setting basic functions, see page 181
2. Setting rotation direction and maximum travels for the servos, see page 183
The basic functions of the model can be controlled once these steps are
completed.
The basic functions can be extended and fine-tuned as follows:
3. Using ailerons as spoilers, see page 187
4. Using camber-changing flaps as spoilers, see page 188
5. Using further optimisation options, see page 188
8.1.2 Basic settings
1. Switch on the transmitter.
2. Open the Memory main menu.
3. Open the New model menu.
4. Select the GLIDER+ model template as Template.
Creating and customising models

PROFI TX
Page 183
8.1.3 Adjusting rotation direction and maximum travels for the servos /
control surfaces
Use electronic means as little as possible to reduce the servo travels. Otherwise,
you will forfeit servo resolution!
If possible, implement major changes using control surface linkages.
8.1.3.1 Configuring aileron differential
1. Open the Mixer > Differnt.Ail menu.
2. Set Mode to ON and Differnt.Ail to 100%.
3. Set aileron travel to the left.
In case of stick travel to the left, the left control surface should move.
If the right control surface moves, reverse the differential using the REV/CLR
button (-100%).
4. Now, reset Differnt.Ail to 50% (+ or -). The suitable value is determined
later in flight.
8.1.3.2 Setting control surface travel and maximum servo travel
If the definition is unchanged, the AILERONS+ mixer is defined as follows:
Fig. 18: Principle of the AILERONS+ mixer
1. Open the Servo > Calibrate > 1: AILERONS+ menu.

6. Choose a P1 setting so that the left aileron (servo 1) stops a little way from
the mechanical stop.
7. Now open P5.
8. Press the F button.
Both ailerons move to the opposite maximum.
9. Set the positive travel on the left aileron (servo 1) to a safe value.
10. You can use the points P2 and P4 to linearise the control curve, if required.
P3 shifts the neutral position without changing the other points.
11. Open the Servo > Calibrate > 5: AILERONS+ menu.
12. Open the REV/TRM parameter and set aileron travel to the right.
If the right aileron does not move up, reverse the servo using the

8.1.3.5 Adjusting flaps
1. If your model has inboard flaps perform step 1 to 4 in section 8.1.3.1
"Configuring aileron differential" on page 183 for the inboard flaps.
2. If your model features mechanical airbrakes, extend them using the assigned
controls. Check and correct the actuation direction in the Servo > Calibrate
menu for servos 8 and 9.
8.1.3.6 Adjusting the power system
1. If your model has a power system, check the actuation direction of the throttle
channel.
2. To switch the throttle channel, reverse the servo using the REV/CLR button.
After these steps, the main setup is completed:
The control surfaces move in the correct direction.
Maximum travels and neutral positions are adjusted.
The ailerons move synchronously.
8.1.4 Using ailerons as spoilers
To use the ailerons as airbrakes (spoilers) proceed as follows:
1. Open the Mixer > AILERONS+ menu.
2. Set the value for the Spoiler > Travel parameter to 100%.
3. Move the control for the Spoiler control function to maximum.
If both ailerons do not move up, reverse the travel using the REV/CLR button.
4. Reduce the value for the Aileron > Travel parameter to a value significantly
below the spoiler travel. Use the manufacturer specifications for your model as
a guideline.
5. Configure the differential in the Mixer > Differnt.Ail menu (see section
8.1.3.1 "Configuring aileron differential" on page 183).

8.1.5 Using camber-changing flaps as spoilers
If your model has inboard flaps, you should use the camber-changing flaps also as
airbrakes (spoilers):
1. Open the Mixer > FLAPS+ menu.
2. Set the value for the Spoiler > Travel parameter to 100%.
3. Move the control for the Spoiler control function to maximum.
If both flaps do not move down, reverse the travel using the REV/CLR button.
4. Reduce both travel distances, up and down, of the aileron.
In this mixer, you can adjust the travel distances of the ailerons separately.
The flaps should have the travel recommended by the manufacturer of your
model.
5. Configure the differential in the Mixer > Differnt.Ail menu (see section
8.1.3.1 "Configuring aileron differential" on page 183).
8.1.6 Optimisation
Your model is now configured and ready for flying. The following optimisation
options are available:
Camber-changing flaps:
Increase the travels for Flap in the mixers AILERONS+ and FLAPS+ (see
section 5.5.2.4 "Mixers on the servo side" on page 137).
Snap flap:
Increase the travels for Elevator in the mixers AILERONS+ and FLAPS+.
You can configure the mixer input as switchable by assigning a switch to the
Elevator mixer input in the SETUP > Define mixer > AILERONS+ menu and
the SETUP > Define mixer > FLAPS+ menu (see section 5.3.7 "Define mixer"
on page 105).
Elevator compensation:
You can mix Spoiler, Flap and Throttle into the elevator using the Mixer >
ELEVATOR+ menu (see section 5.5.2.4 "Mixers on the servo side" on page 137).
Combi-Switch:
Define a switch in the Setup > Assign.Switches menu and assign it in the
Mixer > Combi-Switch menu (see section 5.5.1.1 "Combi-Switch" on page 127).

Other control functions:
If required, assign other control functions to unused servo channels in the
Servo > Assignment menu (see section 5.6.2 "Assignment" on page 142).
V-TAIL+:
In the Servo > Assignment menu, reassign servo channels 2 and 3 from
ELEVATOR+ / Rudder to V-TAIL+.
Then, adjust the rotation direction and travels in the Mixer > V-TAIL+ menu
(see section 5.5.2.4 "Mixers on the servo side" on page 137).
Flight phases:
Assign a switch to flight phases 1 to 3 in the Setup > Assign.Switches
menu.
The 4th phase is activated by a assigning a switch to Phase 4.
Choose a suitable name for each flight phase in the Setup > Flight phases
menu. Set the transition time to the next phase using the Slow parameter
(see section 5.3.2 "Flight phases" on page 94).
Flight phases as virtual switches:
You can also assign flight phases as virtual switches, e.g. if you prefer to use
different mixers in some flight phases.

8.2 Helicopter models
8.2.1 The procedure in principle
A model memory for a helicopter with 120° CCPM rotor head and electric power
system is created in this example.
The following steps are required to ensure correct operation of the basic model
functions:
1. Creating a new model in the transmitter, see page 190
2. Preparing controls and switches, see page 191
3. Checking and changing servo assignment, see page 194
4. Checking and adjusting the main rotor, see page 195
5. Checking and adjusting the tail rotor, see page 201
The basic functions of the model, i.e. Aileron, Elevator, Rudder, and Throttle /
Collective, can be controlled once these steps are completed.
The basic functions can be extended and fine-tuned as follows:
6. Working with flight phases, see page 207
8.2.2 Creating a new model in the transmitter
1. Open the Memory main menu.
2. Switch to a similar model in the select menu. If no model is available yet or if
the current model is quite similar to the new model, simply proceed with the
next step.
3. Open the new model menu in the Memory main menu.

Selecting a template
Thanks to pre-defined model templates (see page 53) new models can be created
more easily and quickly since the basic configuration is more or less completed by
selecting the template.
You can use the Memory > Edit name menu to find out which template was used
for model creation.
4. Select the HELIccpm model template for the Template parameter.
Inheriting parameters from the active model
5. Select the data to be inherited from the currently active model.
a. Ctrl Mode: Usually, the basic control functions will always remain on
the same stick axes. So, keep the switch setting "ON".
b. Ctrls assignment: When you select "ON", the assignments of controls
to control functions are inherited from the current model. When set to
"OFF", they are inherited from the template.
c. Switch assignment: When you select "ON", the assignments of
switches to switched functions are inherited from the current model.
When set to "OFF", they are inherited from the template.
d. Names of Controls: When you select "ON", the names of the control
functions are inherited from the current model. When set to "OFF",
they are inherited from the template. If you changed the names in the
current model and you would like to inherit these names, "ON" should
be selected. Otherwise, setting the switch to "OFF" is preferable.
e. Sensor names: When you select "ON", the names of the sensors are
inherited from the current model. When set to "OFF", they are inherited
from the template. If you changed the names in the current model and
you would like to inherit them, "ON" should be selected. Otherwise,
setting the switch to "OFF" is preferable.
The device stores your selection. In most cases, you just have to check the
selection switches.
Confirming settings
6. Confirm the setting with OK: The model memory is created and immediately
activated. The display automatically switches to safety check and status
display.

Editing the model name
The new model that is created has the same name as the template used: HELIccpm.
For easier reference, you should change the name to the actual model name:
7. Open the Memory > Edit name menu.
8. Enter a name (max. 16 characters) that clearly identifies the model. Refer to
page 157 for details.
The creation of a new model in the memory is now completed. These settings
determine the following in the model memory:

Unused switches are marked with „ --- -" and are not listed here.
9. Assign a switch to all the switched functions that you intend to use.
You can now perform the first functional test with the servo monitor. The model is
not required for this test (see section 5.6.4 "Test run" on page 144).
8.2.3 Preparing controls and switches
Checking / changing the minimum control positions for idle / collective pitch
and throttle limiter
In the templates for helicopters, minimum idle / collective pitch is set to "back"
(# arrow next to the identifier). The minimum position for the throttle limiter is also
set to "back".
To change the setting to "front" proceed as follows:
1. Open the Setup main menu.
2. Open the Assign.Controls menu.
3. Select the control function, e.g. Throttle.
Creating and customising models

4. Operate the throttle stick vigorously. Leave it in idle position.
The direction arrow points to the current position of the stick.
Never change the assignments and/or rotation direction of controls and switches
when the model is switched on. Power systems and servos may start up
unexpectedly and cause damage.
5. Confirm the change by pressing ENTER.
Proceed as described above to change the minimum position for the throttle limiter.
Changing switch position for ON and/or assignment
The "ON" position can be changed for all the switches.

8.2.4 Checking and changing servo assignment
The servo assignment defines:
The receiver output controlling the servo
The number of curve points (2, 3, or 5) used for adjusting the servo travel
Defaults
The rotor head servos and the servo gyro have 3 curve points (the centre can also
be set). Throttle and tail rotor have 2 curve points for a linear characteristic (only
end-points must be set).
Procedure
1. Open the Servo main menu.
2. Open the Assignment menu.
In this menu, the assignments for all the receiver outputs can be changed as
required.
In the following example, servos 3 and 4 are swapped so that all the head
servos are in sequence.
3. Select servo 3 TAIL ROTOR.
4. Press ENTER. Use the central wheel to set MAINROTOR-R.
5. Press ENTER. Set the number of curve points to 3P.
6. Press ENTER. Select servo 4.
7. Press ENTER. Use the central wheel to set TAIL ROTOR.
Creating and customising models
PROFI TX
8. Set the number of curve points to 2P. Only the end positions then require
setting. This always yields a straight line between the points.

8.2.5 Checking and adjusting the main rotor
Secure the model when you set the rotation direction, centre, and travels for the
servos to prevent danger or damage due to unexpected reactions.
8.2.5.1 Checking / changing direction of servo rotation on the rotor head
The directions of travel for the servos must be checked and changed (if required)
before centre and travel are set.
For electric helicopters: disconnect the motor!
Move the collective pitch stick approximately to the centre position.
Then, switch the receive system ON.
Start with the Collective function!
If swashplate responds correctly when you move the collective pitch stick and if the
head servos are connected correctly, the directions of travel for aileron and elevator
must also be correct.
To perform the check move the collective pitch stick in the direction of maximum
collective pitch (climbing) and observe if the swashplate moves up and remains
horizontal.
Changing the rotation direction
1. Open the Servo main menu.
2. Open the Calibrate menu.
3. Select a servo.
4. Select REV/TRM and open the parameter.
5. Adjust the direction of servo rotation using the REV/CLR button. The effect of
the change is immediately visible in the graph (the curve reverses).
Creating and customising models
PROFI TX
If you move the collective pitch stick slightly from the neutral position before
pressing the REV/CLR button, the servo will jump to the new position when you
reverse it. This is an easy way to check that you have selected the "correct" servo.
6. If the rotation direction is correct, confirm the change and exit the menu.
7. Select the next servo that you want to edit.
Make sure that the rotation direction for all the servos is correct before you start
to set travel and centre. If the rotation direction is changed later, you will need to
re-calibrate it.
8.2.5.2 Calibrating servos: setting centre and maximum travel
Use the Servo > Calibrate menu (see page 139) to adjust the travels (P1 and P5)
and the centres (P3) for all the servos so that the servos take up the correct idle
position, move evenly across their range of travel, and reach the appropriate
end-points.
If you wish your models to fly accurately, precise servo calibration is a fundamental
requirement!
The travel you set at this point cannot be exceeded (travel limit).
Always set the largest travel which the servo will be required to carry out.
Setting the centre
1. Open the Servo main menu.
2. Open the Calibrate menu.
3. Select a servo.
4. Select the P3 menu item and open the parameter.
Creating and customising models
PROFI TX
Page 199
First, perform a hardware calibration:
Press the F button. This generates the "true" centre, without the influence of the trim
or mixer inputs on the servo.
If the servo is not in the desired centre position at this stage, it is essential to correct
the control surface position mechanically (by re-positioning the output arm on the
servo, or otherwise adjusting the linkage).
Wherever possible, the fine-tuning for point P3 for the servo calibration should not
exceed ±15%.
5. Press the F button to allocate the centre. This passes the Centre value, 0%, to
all the servos with the same basic function. This enables you to set the centre
for the current servo regardless of the stick position.
Moving the stick, or pressing the F button erases the allocation!
Note regarding "allocation"
Allocating in this way saves you the bother of holding the stick at one end-point, and
enables you to use both hands in order to measure the control surface travel on the
model. If required, you can make corrections using the central wheel.
Calibrating multiple servos with the same function:
Example:
Servos 1, 2, and 4 are assigned as MAINROTOR-X (mixed function). Point P3 is
opened in the Calibrate menu for servo 1. When you now allocate the centre
using the F button, all the swashplate servos will immediately move to the centre.
At this point, you can use the central wheel to adjust the current servo to match the
other two.
6. Use the wheel to set the servo to the desired centre. Any changes you make
are immediately visible on the model itself.
7. If the centre is correct, confirm the change and exit the menu.
8. Select the next servo that you want to edit.
Creating and customising models
PROFI TX
Setting the maximum servo travel (control surface travel)
At this point, set the maximum required value for blade deflection; this is generally
the auto-rotation value. The smaller values required for normal flying can be set for
the individual flight phases in the ControlFunctions menu under Collective.
1. Open the Servo main menu.
2. Open the Calibrate menu.
3. Select a servo.
4. Select the P1 menu item and open the parameter.
5. Press the F button. All the swashplate servos now assume this position.
This enables you to set the servo travel regardless of control position and trim.
Pressing the F button again unlocks the servos.
Maximum servo travel = ±110%
If required, servo travel can be increased to up to 110% on both sides.
6. Conclude the calibration for P1.
7. Repeat the procedure for point P5, starting from step 4.
8. Exit the menu and set up the other servos accordingly.

8.2.6 Checking and adjusting the tail rotor
8.2.6.1 Checking / changing the direction of servo rotation for the tail rotor
The direction of servo travel must be checked and changed (if required) before
centre and travel are set.
When entering the basic settings do not connect the tail rotor servo via the gyro, but
directly to the respective receiver output. This ensures that the gyro has no effect on
your settings.
Move the rudder stick to the left, and observe the response of the tail rotor. Does
the pitch angle of the blades change in the correct direction? Otherwise, reverse
the tail rotor servo as described on page 141.
8.2.6.2 TAIL ROTOR mixer
The TAIL ROTOR mixer of the PROFI TX conceals the function "static tail rotor
compensation", which is also sometimes known as REVO-MIX (revolution mixer).
The TAIL ROTOR mixer is always displayed in the Mixer main menu when you set
up a model based on the model templates HELImech. or HELIccpm.
When a helicopter makes the transition from the hover into a climb or descent, the
torque which the tail rotor has to compensate becomes larger or smaller, with the
result that the model yaws in one direction. Once set up correctly, the TAIL ROTOR
mixer compensates for these torque fluctuations, and prevents the model yawing.
It also eases the task of the gyro system, so that you can set a high sensitivity
value and thereby obtain very good tail rotor stabilisation.
For this, the following parameters are required in the TAIL ROTOR menu:
Offset
To compensate for the torque at 0° collective pitch (main rotor), a small tail rotor
pitch angle (= Offset) is required. The value can be set separately in each flight
phase. This will be necessary if you use different system speeds in the various
flight phases.
In the flight phase AUTOROT (auto-rotation) the Offset parameter can be changed
so that no tail rotor pitch is present at all. This is particularly important if your model
helicopter features a driven tail rotor.
Creating and customising models
PROFI TX
Coll.+ / Coll.- (REVO-MIX)
You can use the Coll.+ / Coll.- parameters to set the collective pitch mixers for
the tail rotor separately for climb and descent, and for each flight phase:
Coll.+: correction for climbing
Coll.-: correction for descending
The exact values can only be established through a programme of flight testing,
and vary according to many parameters.
Zero point
The origin for the static tail rotor compensation mixer is set under Zero point.
Starting from this collective pitch setting angle in the direction of "climbing", the
"Collective -> Tail rotor" mixer is added using the value set for Coll.+. The value
set for Coll.- is applied in the other direction (descending).
1. Move the collective pitch stick to the position corresponding to 0° collective
pitch (use a rotor blade gauge if available).
The setup of the collective pitch curve must be completed, first.
The value for Collective (last line) cannot be changed. It shows the current position
of the collective pitch stick, and serves as an aid during setup. Use the throttle /
collective pitch stick to set the main rotor blades to a pitch angle of zero. Apply this
value to the Zero point parameter.
Configuring rudder differential
The purpose of the Rudd.Diff. parameter is to reduce the tail rotor travel in one
direction. This is necessary if the model behaves differently when yawing (rudder
commands) to left and right (angular velocity). Since the tail rotor has to counteract
the torque generated by the main rotor, "Rudder" is usually weaker when the model
is required to turn against the rotation direction of the main rotor.
A separate value can be set for each flight phase.
Creating and customising models
PROFI TX
Page 203
8.2.7 Gyro
The Gyro control function is intended for gyro systems which allow radio-controlled
configuration of the sensitivity via a servo channel.
If Gyro is not assigned to a servo channel, this function is not available in the
Controls menu.
1. Open the Controls main menu.
2. Open the Gyro menu.
The gyro type Heading is selected by default in the model templates. The fixed
value for sensitivity setting is switched off (OFF). Gyro sensitivity is controlled using
the assigned control. In the helicopter templates, this control is always the left-hand
slider (<E). The next line shows the operating mode (Mode), the value provided by
the control in %, and the identifier for the control (<E). Rudder is set as
Controlled axis.
In Heading mode, rudder trim and tail rotor mixer (TAIL ROTOR) are switched off.
The gyro is assigned to servo channel 6 in all the helicopter templates.
Refer to section 5.4.5 "Gyro" on page 122 for more information.
Damping mode
The gyro operates in Damping mode if you set the sensitivity to a value
between 0% and +100%:
The gyro operates in Heading-hold mode if you set the sensitivity to a
negative value.
Controls mode
Creating and customising models
PROFI TX
In controls mode, gyro sensitivity can only be set manually using the Gyro
control function (factory setting: slider E). To this end, Fixval.Sense must be
set to OFF. The next line now shows the position (50%) and control (<E):
8.2.7.1 Setting gyro suppression
Many gyros reduce their effect (sensitivity) when the pilot gives a deliberate
command. Without this suppression, the gyro would also damp out intentional
control commands. If you are using a gyro without its own automatic suppression
(read the appropriate notes in the gyro system operating instructions!), then you
should activate this function.
In helicopter models, the gyro effect is suppressed in proportion to the travel of the
control that was set in addition to the Controlled axis. In case of helicopters,
this control is always Rudder.
If Suppression = 100%, the gyro effect (Fixval.Sense) is reduced to
zero (= gyro OFF) at full travel of the Rudder control.
If Suppression = 200%, gyro sensitivity is reduced to zero (= gyro OFF)
at half travel of the control.
If Suppression = 50%, gyro sensitivity at full travel is 50% of the original
value setting.
Suppression is only effective in the Damping gyro mode, regardless of the flight
phase.
Before flying a model, make sure that the gyro counteracts the rotational movement of
the model in Damping mode. If set incorrectly, the gyro will amplify any unwanted
yawing motion of the helicopter model, rendering it uncontrollable.
Please observe the notes in the operating instructions supplied with the gyro system!

Page 205
8.2.8 Throttle
Does not apply to the FUNCOPTER template! For throttle-controlled helicopters, the simple
throttle setting of fixed-wing models is used. See chapter 5.4.2 on page 117.
The Throttle control function can be adjusted using 7 curve points or using
a fixed value when the electric power system operates in Governor mode.
Each flight phase has a specific curve. Only in the AUTOROT flight phase, all the
curve points have the same value (yielding a straight line).
To assist model adjustment when the motor is running Throttle can be limited
towards full throttle using a limiter. In all the helicopter templates, the right-hand
slider F> is used for this function (changing; see page 101). During adjustment,
reduce the limiter to a value that prevents the model from taking off.
The purpose of the throttle cut switch is to turn off the power system quickly
in case of an emergency.
No Throttle-Cut switch is assigned in the templates. You must assign a switch
before you start operating your model (see page 104). Always use a dip-switch.
If a button were used, electric motors would start up again when the button
was released!
The limiter (upper dashed horizontal line) limits the throttle upwards to allow
the model to be adjusted (slider at the top = no limit). The sum of lower
limit + trim
FPH
restricts Throttle downwards as the idle limit for I.C.
engines (upper dashed horizontal line).
The idle limit is switched off in the AUTOROT flight phase, even if flight phase
specific trim was or is set to 0.0%.
Creating and customising models
PROFI TX
Sometimes, it can be useful to operate the throttle directly without any restrictions.
To do so, assign a switch to the CS/DTC switched function as described on
page 104. When this switch is in ON position, the limiter controls the throttle
directly.
8.2.9 Setting the collective pitch curve
Does not apply to the FUNCOPTER template! Throttle-controlled helicopters do not feature
collective pitch control.
For helicopter models, the collective pitch curve is set in the ControlFunctions
menu under Collective. For each of the flight phases a separate collective pitch
curve can be configured to achieve optimum adaptation to the respective flight
phase:
Each curve point can be allocated using the central wheel to allow in-flight configu-
ration (see section 5.4.6 "Collective (only helicopters)" on page 125).
Example 1: collective pitch curve in the HOVER flight phase
A "flatter" collective pitch curve from hover collective pitch (stick centre) to
collective pitch minimum (descent) helps to provide fine control during the hover
and promote accurate landing of the model.
In the "climb" area (stick centre to collective pitch maximum) only 70% of possible
collective pitch travel is used. This also contributes to fine control during the hover.
Example 2: collective pitch curve in the CRUISE flight phase
Linear, symmetrical collective pitch curve for the same collective pitch control when
climbing and descending; overall higher maximum collective pitch values since a
higher system speed is typically set (throttle curve) allowing higher climbing
performance:

8.2.10 Working with flight phases
Requirement
To allow working with flight phases, at least one switch must be assigned in the
Setup > Assign.Switches menu (either for Phase 4 or Phases 1-3).
Otherwise, the transmitter always operates in Phase 1.
For each flight phase, you can customise the control characteristics on the
transmitter according to the requirements of the model (e.g. reduced control travels
for HOVER, maximum control travels for collective pitch for AUTOROT, V-shaped
throttle curve for 3D flying). In the control function menus, all settings that can differ
between flight phases are accompanied by the respective identifying number for
the flight phase.
Example: Aileron
Flight phase specific settings can only be configured for control functions and control
mixers. The servo settings are identical in all the flight phases.
8.2.10.1 Defaults in the Flight phases menu
1. Open the Setup main menu.
2. Open the Flight phases menu.
Flight phases 2, 3, and 4 are locked (the name is crossed out).
Three dashes "---" next to the flight phases indicate that no switch has been assigned
for switching between flight phases. In this case, flight phase 1 HOVER is automatically
selected and marked as the active flight phase (x).
Creating and customising models
PROFI TX
Names are pre-assigned to all four possible flight phases. However, those can be
edited using the + / – button or the central wheel.
8.2.10.2 Assigning switches for flight phases
At least one of the two switches must be assigned before you can use different
control settings in the flight phases:
1. Open the Setup main menu.
2. Open the Assign.Switches menu.
3. Select Phases 1-3 and open the parameter.
4. Move switch I to the ON position (* must be visible).
To use all four flight phases a switch must also be assigned to Phase 4.
Phase 4 switch (assign a 2-position switch)
If this switch is in ON position (marked with * during assignment), flight phase 4
is activated. In this case, the position of the second switch does not have any
influence.
If no switch is assigned to Phases 1-3, you can only switch between phase 1
and 4 by operating the Phase 4 switch.
Phase 1-3 switch (assign a 3-position switch)
You can use this switch to activate Phase 1, 2 or 3, provided that the Phase 4
switch is in OFF position.
8.2.10.3 Locking / unlocking flight phases
You can lock flight phases that have not yet been set. Locked phases cannot be
activated even if a switch is assigned to them. If the switch is moved to a position
for a locked flight phase, an acoustic warning sounds (a beep approx. every
0.5 seconds) for as long as the switch remains in this position.
The active flight phase—marked with an x—cannot be locked.

1. Open the Setup main menu.
2. Open the Flight phases menu.
3. Select the respective flight phase in the menu.
4. Every time you press the REV/CLR button, the flight phase toggles between
locked and unlocked.
5. Confirm the change.
8.2.10.4 Copying flight phases
Once you have established the correct settings in one flight phase, you can copy
the values into another flight phase and then modify them. This avoids the need to
re-enter all the settings from the start.
Only the active flight phase can be copied.
1. Open the Setup main menu.
2. Open the Flight phases menu.
3. Select the active flight phase (with the X) and press the ENTER button twice:
A C is now shown above the X.
4. Select the copy target by moving the C to the respective line. Press the ENTER
button.
The cursor returns to the number of the active flight phase. Except for the run
times, all the flight phase specific settings are now identical to those of the
active flight phase.

Maintenance and care
PROFI TX
Page 211
9 Maintenance and care
The transmitter does not require any special maintenance or care.
However, we strongly recommend that you have the transmitter checked by an
authorised MULTIPLEX Service Centre at regular intervals (every two or three
years), depending on the intensity of use. Regular functional and range checks are
mandatory (see section 3.6 "Range check" on page 47).
Never use abrasive cleaning agents such as spirit or solvents!
Remove dust and dirt preferably with a soft bristle brush.
Remove persistent dirt, in particular grease and oil, with a moist cloth and,
if required, with a mild household cleaning agent.
Protect the transmitter against mechanical impact and shock.
The transmitter should be stored and transported in a suitable container (bag
or carrying case).
At regular intervals, check that the transmitter case, mechanical parts and
especially the wiring and contacts are in good condition.

Glossary of technical terms
PROFI TX
Page 215
Glossary of technical terms
Allocation
Permanently assigning a set value to a digi-adjuster.
Assignment
Defines which functions in the transmitter or model are controlled by which control.
Battery management
Determines the remaining operating time (time to empty), the capacity and other
battery data from the current and voltage characteristics. Optimises the charge /
discharge limits for a long battery life.
Binding
Required to ensure that the receiver exclusively responds to signals from "its"
specific (bound) transmitter. The binding procedure must be performed during
initial setup.
Re-binding is required if the transmitter mode is changed (e.g. response is
changed from "Fast" to "Normal", frequency range is changed from "Normal"
to "France").
Centre trim
Trim corrections do not change the end-points.
Combi-Switch
Couples aileron and rudder in a way that allows both of the control functions
to be controlled by either of the functions. This makes it easier to fly accurate
turns.
Control
Any transmitter control which can be assigned to a control function or switched
function:
o Sticks
o Slide potentiometers
o Rotary potentiometers
o Switches and their designated buttons
Glossary of technical terms
PROFI TX
Differential
Indicates the percentage by which the travel distance of the control surface
down is reduced relative to the travel distance up; if the differential is set to 50%,
the travel distance down is half as great as the travel distance up. The higher
the % value, the shorter the travel distance of the control surface down.
Differential is required because the downward control surface generates greater
drag than the upward control surface. This results in a negative turning moment
(known as adverse yaw) which tends to push the model out of the turn.
Digital trim
The physical position of a conventional trim with trim slider corresponds to the
actual trim value, while digital trim buttons do not. The digital trim position is
displayed on the screen, and the trim values are stored in the model memory.
If you switch model memories, there is no need to move the trim sliders to the
correct position to suit the model. The correct trims are immediately available.
If the PROFI TX is used with a model for which you have set up multiple flight
phases, each flight phase has its own trim memory, i.e. it is simple to trim each
flight phase accurately, and independently of the trims in the other phases.
DTC
Direct Throttle Control
If DTC is switched on, the throttle channel (regardless of whether it acts upon a
carburettor or a speed controller) is controlled directly by the transmitter control
assigned to throttle limiter, and is independent of the position of the collective
pitch stick.
Dual rate (D/R)
Alters the sensitivity of particular transmitter controls. If the D/R parameter for a
control function (e.g. Aileron) is set to 50% you can use the assigned switch to
reduce the control surface travels on the model by half for finer control. The
control curve in the graph changes accordingly when you operate the switch
assigned to dual rate.
Glossary of technical terms
PROFI TX
Page 217
Expo
Generates a non-linear control function.
For Expo = 0%, the control works in a linear fashion.
The effect of negative values is that smaller control surface travels are
generated around the centre position with the same stick travel, thus
providing finer control.
The effect of positive Expo values is that control surface travels are
increased around the centre position.
The end-points remain unchanged.
Failsafe
If the receiver does not receive any signal, the servos stop at their most recent
positions (Hold function). If Failsafe positions were stored in the receiver, the
servos return to these positions after 0.75 seconds.
FastResponse
Reduces the transmission cycle from 21ms to 14ms reducing the response time
for control commands. Only 12 servos can be controlled with FastResponse.
Flight phases
Settings / data sets for a model which can be called up by operating a switch.
The data sets are optimised for particular flight tasks.
Lower throttle limit and throttle trim (idle)
You use the lower throttle limit to restrict the throttle channel to the idle speed
of the power system.
If you set the throttle limiter to minimum, the idle characteristics of an I.C.
engine can be fine-tuned using the trim in order to suit the operating conditions
(temperature, humidity). Trimming is carried out using the trim button adjacent
to the stick which you have selected (via "Mode") to control throttle and
collective pitch.
MagicSwitch
Logical switch, which can be assigned like a normal control; it combines up
to three switches in an AND function. Unused inputs are considered switched
on. In addition, switching can be delayed.
Mixer
Combination of control functions (e.g. elevator, aileron, etc.) in various
percentages; 14 free mixers are available in PROFI TX. Five of these
mixers are pre-defined and ready for immediate use. All the mixers (even
the pre-defined ones) can be changed as required.
Glossary of technical terms
PROFI TX
Mode
Defines the assignment of the main control functions Aileron, Elevator,
and Rudder to the stick units.
Model template
Template for creating new models; thanks to model templates, new models
can be created more easily and quickly since the basic configuration is more
or less completed by selecting the template. Model templates also contain
the basic configuration for mixers, controls, servos and flight phases.
Range check
Is used to check the proper operation of the radio link. The transmitter power
is reduced to approx. 1% so that the check can be performed at a shorter
distance.
Ratchet
Ratchet system in which a mechanism assumes and holds a specific position.
Servo
Positioning device; converts a default setting that is provided as an electrical
signal into a physical position.
Servo calibration
Servo curve
Used to define the maximum control surface travels, set the neutral position,
and set the control surface travels of servos with the same function to the
same value. Also for trimming servos on control surface pairs to synchronous
operation.
Snap flap
Switchable elevator mixer to the camber-changing flaps (flaps) or the ailerons.
Spoiler
Used for glide path control or for "braking" the model.
Standard trim
Shifts the entire setting range of the stick in parallel up and down (by the trim
value). To allow this shift without limiting the control signal, the control signal
must be reduced by the maximum trim value possible. Thus, unlike centre trim,
the servo travel cannot be fully used.
Switch
Controls that switch functions on or off or toggle between functions; multiple
menus are available for assigning switches to functions. Standard functions
(D/R, Timer, etc.) are compiled in a list.
Glossary of technical terms
PROFI TX
Page 219
Throttle curve
Only used for helicopters. The throttle curve of the PROFI TX has 7 points and
determines how much throttle is assigned to the various individual positions of
the collective pitch stick. The aim is a constant speed, i.e. the higher the
collective pitch, the more the throttle is advanced.
Throttle limiter
Only used for helicopters. Restricts (limits) the maximum possible throttle value.
This allows safer model setups. For normal flying, the limiter is set to maximum.
After start-up of the power system, the throttle limiter can be used to slowly
increase the speed of the main rotor.
Throttle-cut
While this switch is switched on, the throttle channel is maintained in the
position which you earlier selected during travel adjustment as point P1 for the
throttle servo. This enables you to "switch off" an I.C. engine, assuming that the
carburettor barrel is fully closed at this position.
Trainer mode
Safest method for beginners to get started in model sport; two transmitters are
inter-connected using a second M-Link radio link. An experienced modeller has
control over the model, and is able to transfer control functions to the student by
operating the trainer button ("TEACHER" button). Initially these will be individual
control functions, and later all the main control functions when the "student" has
gained sufficient skill. If individual control functions are transferred, the teacher
retains control over the remaining control functions. If he releases the
TEACHER button, the teacher resumes full control of the model—typically if a
dangerous situation develops. The teacher transmitter carries out all the data
processing. This means that the student transmitter simply needs to be
switched to "Student" mode. No further configuration or programming is
required. All the teacher transmitter needs from the student transmitter are
the pure stick signals.
Trimming
Adjustment of the model aircraft to fly straight and level when you leave the
sticks exactly at centre.
Variometer
Device in the model aircraft that indicates the climbing and descending rate
through audible signals.
