ing this system.

•FEATURES

The FP-8SSAP was specially developed to use PCM (pulse code modulation) for FAI

RC aerobatics F3A aircraft. It is an extremely noise and dead-point resistant digital

proportional RC set with a microprocessor in the transmitter and the receiver. Please

read this manual before using your set.

TRANSMITTER FP-T8SSAP

• RF module system. The frequency band can be

changed with one touch.

• DSC (Direct Servo Controller) allows operation

of the servos without turning on the transmitter.

Wire operation is possible by using the special

cord supplied (FSC.1).

•Servo reversing switch for all channels allows

reversing

of the

servos

with

the

flip

switch.

• Dual rate or non-linear VTR (variable trace

ratio) aileron, elevator, and rudder. Two-stage

dual rate on aileron.

• Rudder auto dual rate. Rudder dual rate is

turned on and off automatically with operation

of the throttle lever.

• Newly designed rotatable open gimbal stick

provide maximum operation feel. Stick position

and spring tension can be adjusted.

• New throttle -> pitch control mixing is perfect

for variable pitch propeller which maximizes

engine power and propeller efficiency.

• Mutual mixing function allows aileron + eleva-

tor, aileron + flaps, and aileron + rudder mixing

and aileron differential operation.

• Elevator -> flap mixing is especially advantageous

in circle aerobatics.

• Flap, spoiler -> elevator mixing allows control of

the aircraft attitude while using the air brake

(flap, spoiler).

• Throttle -> (flap, spoiler) -> elevator mixing

allows enhancement of the air braking effect by

throttle lever operation when diving and landing.

• Programmable mixing function permits mixing

with the desired channel.

• Four-function snap roll switch (Timer is op-

tional).

• Idle-up lever, the engine idling speed can be

independently adjusted during throttle -> pitch

control mixing.

• New single-chip microprocessor allows one-touch

fail safe setting and introduction of an automatic

transmission system which eliminates the need

for fail safe setting at the beginning of each

flight and improves safety.

•Pitch

control

lever.

HIGH

side

pitch

variable

pitch propeller can be adjusted during throttle

-> pitch control mixing.

• New ATV (Adjustable Travel Volume) on all

channels allows independent adjustment of servo

left, right, up, and down throw.

• Second ATV. Besides new pushbutton ATV on

aileron and elevator, conventional trimmer ATV

is also installed.

• Monitor lamp comes on when throttle -> flap,

spoiler -> elevator mixing or throttle -> pitch

control mixing and flap, spoiler -> elevator mix-

ing and snap roll are set and goes out when they

are

use.

• Fail-safe switch (function OFF switch) is pro-

vided for each function so that only the desired

functions need be turned

on.

•Throttle ATL (Adjustable Throttle Limiter)

makes throttle linkage simple and positive.

• Two servo test functions. A slow sweep to check

neutral characteristic, trackability cycle servo to

test servo operation.

•Tachometer/timer with built-in tachometer, up

timer, down timer, integrating timers, and bat-

tery alarm functions.

• Built-in power error back-up circuit. When the

internal Nicd battery approaches the fully dis-

charged state, an LED flashes to indicate that

the memories presetted (memory, ATV, FS,

etc.) are gone. Please charge battery and set all

memory functions again.

RECEIVER FP-R118GP

•The

receiver

of this

set

miniature

PCM

re-

ceiver in which the highest reliability has been

pursued. It is the first R/C receiver in the world

to incorporate the newest computer technology.

• Miniature PCM receiver with high speed single

microprocessor. Resistance to adjacent band and

spark noise interference has been increased by

one full order of magnitude.

• Microprocessor servo hold function eliminates

erroneous

operation

when

"dead

point"

area

is entered.

• Microprocessor provides fail safe and battery fail

safe functions for greater safety.

• Error lamp display allows checking of the receiv-

er operating state.

• DC-DC converter in the power supply improves

low-voltage operation characteristics.

• High sensitivity design with RF amplifier.

• Ultra narrow-band ceramic filter and PCM sys-

tem are invulnerable to adjacent band inter-

ference.

• Gold plated connector pins eliminate poor con-

tact. Polarized housing improves reliability

against shock and vibration.

• DSC circuit. Each servo can be controlled from

the transmitter without turning on the transmit-

ter by connecting the transmitter directly to the

C terminal.

SERVO FP-S130

•Small, double ball bearing, water-tight & dust-

tight servo. High output torque 55.6 oz-in (5kg-

cm), high-speed .24sec/60°.

• New indirect drive potentiometer improves

vibration and shock resistance and neutral

precision.

• Futaba low-power custom 1C provides high start-

ing torque, narrow dead band, and excellent

trackability.

• Fiberglass reinforced PBT (polybutylene ter-

ephthalate) molded servo case is mechanically

strong and invulnerable to glow fuel.

• Strong polyacetal resin ultra-precision servo gear

features smooth operation, positive neutral, and

very little backlash.

•

•Since forward/reverse operation is controlled by

the pulse width of the signal generated by turn-

ing the transmitter snap switch on and off, the

motor stops at the end of its throw in either

direction.

• Unlike other proportional servos, motor drive

current does not flow when the servo is stopped

even if a load is applied. Thus current drain is

extremely low.

GLOSSARY OF TERMS

NOTE: Please take the time to familiarize yourself with the terms and abbreviations

below. They will be used throughout the instructions and are important in understand-

ing the operation and potential of your system.

PCM (Pulse Code Modulation) SERVO REVERSING

Pulse Code Modulation utilizes a precise digital

code to convey information from the transmitter

encoder to the receiver. This state of the art meth-

od makes many of the sophisticated functions of

the FP-8SSAP possible, as well as providing far

superior immunity to noise and interference than

is possible with conventional encoding methods.

ATV (Adjustable Travel Volume)

This feature allows independent adjustment of

servo travel in each direction. ATV is sometimes

referred to as "endpoint adjustment". Two dif-

ferent types of ATV are standard with this system,

(1) Pushbutton or Programmed (Memory) ATV

and (2) 2nd ATV (Conventional).

MEMORY ATV

This type is available on all eight channels. These

adjustments are stored in the transmitter memory

circuit and are retained when the power switch is

turned OFF. They are lost however, if the trans-

mitter Nicd batteries reach full discharge.

2ND

ATV

Available on Aileron (CH 1) and Elevator (CH 2).

This is the conventional type ATV which is set by

using trimmer pots on the transmitter back panel.

These settings are NOT affected if the transmitter

batteries are discharged.

DUAL RATE

Rate switches allow the pilot to select different

servo travel limits (for varying control sensitivity)

in flight. Servo travel is affected equally in both

directions from center.

SAFETY (ACT/INHIB)

SWITCHES

These switches, located on the transmitter trimmer

panel allow mixing and certain other functions to

be deactivated when not desired. When the Safety

Switches are set to the INHIB position, the func-

tion will remain OFF even if the transmitter con-

trol switch is set to ON.

VTR (VARIABLE TRACE RATIO)

This is a special type of non-linear control re-

sponse. When VTR is used, servo travel is normal

and linear up to about 80 percent of the transmit-

ter control stick movement where the servo travel

is abruptly increased to a higher rate (both rates

adjustable). This allows a normal feel for most fly-

ing with extra movement available for emergencies

and certain acrobatic maneuvers. Another way to

think of this function is as "automatic Dual Rate".

This function allows the modeler to reverse the

direction of servo movement (in relation to con-

trol stick movement) for various installation re-

quirements. This can be done by conveniently

flipping a switch on the trimmer panel. Servo

travel and neutral position are not affected.

BFS (Battery Fail

Safe)

This function provides a warning to the flyer when

airborne battery voltage reaches a critically low

level by moving the throttle servo to medium slow

or slow position.

ATL (Adjustable Throttle

Limit)

This feature makes adjusting the throttle linkage

much

easier.

The

throttle

trim

lever

affects

only

the LOW or IDLE position and not the HIGH

throttle servo position. Therefore, the linkage can

be set for proper opening at high throttle and the

trim

lever

used

set

the proper idle

speed

with-

out changing the maximum opening.

MIXING

general, mixing functions allow two or more

different channels to be operated by moving a

single transmitter control. Many useful and versa-

tile functions are made possible in this manner.

Three types of mixing functions are provided.

(1) Unidirectional mixing — This function allows

one or more channels to be "slaved" to a "master"

channel. Movement of the master channel control

causes movement of both master and slaved servos

simultaneously. Operation of the slave channel

control however, does not cause movement of the

master channel servo. An example is Aileron/Rud-

der mixing (see page 33) where the Rudder is

slaved to Ailerons for coordinated turns.

(2) Mutual (Bi-Directional) Mixing - With this

type of mixing, two channels are mixed so that

operation of the control for either channel causes

movement of both servos. This is useful in provid-

ing sophisticated functions such as V-tail opera-

tion,

flaprons, and

elevens

tailless

designs.

(3) Switch-Activated Mixing — Two or more-

channels can be programmed so that the servos

involved move to a preset position when a trans-

mitter control switch is pulled or button pushed.

Snap roll switches, roll buttons, and pre-set

flap

switches are examples of this type of mixing.

PROGRAMMED MIXING FAIL SAFE

Unidirectional mixing of any two channels desired

is possible using the pin board and jumper con-

nectors on the transmitter back panel. Either chan-

nel may be designated as "master" or "slave".

DSC

(Direct

Servo

Control)

Operation of the entire system with the transmit-

ter switch in OFF position is possible using the

DSC cord. This is useful for checking and adjusting

control movements on the ground while someone

else is flying on your frequency.

The Fail Safe function moves servos to a pre-set

position if the transmitter signal is lost or inter-

rupted by strong interferrence. The servos will be

held in the pre-set position until a proper signal is

again received at which time Fail Safe is released.

HOLD

The Hold function holds servos at the same posi-

tion

immediately prior

signal

interruption.

Hold is released when a proper signal is resumed.

•Trainer system offers an easy training of flight

for beginners.

•BASIC TRANSMITTER CONTROLS

The servo reversing switches are assumed to be in the normal position in the descrip-

tions in this section. When the reversing switches are in the reverse position, servo

operation is the opposite of that described here.

22 Monitor Lamps

IMPORTANT: In all instructions on control functions. Items designated by a number inside a circle

(For example 10 ) are transmitter controls normally accessable and operated in flight.

Items designated by a number within a box (For example 10 ) are adjustment functions not operated

while in flight.

Lamp A Power Monitor

• When the power switch

23 is set to ON, this lamp flashes on

briefly and then goes out momentarily as the Fail Safe data is auto-

matically matically transmitted to the receiver. Fail Safe data is

transmitted every 60 seconds at which time the lamp also goes out

momentarily. If the transmitter Nicd battery nears full discharge,

this lamp starts blinking, indicating that the power error backup

function is activated. When this occurs, transmitter memory func-

tion settings are lost and must be reset.

Lamp

3 -> 6. 7 -> 2 I 3 -> 8 Mix

This lamp comes on when Safety Switch 7 and/or [33] is set to

ACT position, indicating that throttle —-> flap, spoiler —-> elevator

mixing and/or throttle -> pitch control mixing functions are activat-

ed. This lamp will blink when transmitter control switch II is set

to ON (placing these functions in operation).

Lamp C 6, 7 -> 2 Mix

• This lamp comes on when Safety Switch [32] is set to ON (flap,

spoiler -> elevator mix) or CH7 OFF (flap -> elevator mix) position.

This lamp blinks when transmitter control switch 10 is set to ON.

Lamp D Snap Roll

Fig.1

• When Safety Switch [29] is set to ACT (snap roll function acti-

vated), this lamp blinks. When the Snap Roll switch 13 is pulled,

this lamp continues blinking.

When the power switch 23 is set to ON, lamp (A) will go out momentarily. This indicates automatic data

transmission on and is not a failure.

23 Power switch

• The transmitter power ON-OFF switch is pro-

vided with a locking feature to prevent acciden-

tal movement. To operate the switch, pull the

knob gently outwards and set to the desired

position (UP=ON. DOWN=OFF).

25 Level meter

• This meter indicates the transmitter battery

voltage and output power.

•When the antenna 26 is extended fully and

the power switch 23 is set to ON, the pointer

should move to the white zone.

•If the transmitter RF Module

32 is not

in-

stalled, the meter pointer will not move.

• If the meter pointer moves to the red zone,

indicating that the Nicd battery voltage is low,

the

signal

range

will

become

shorter.

the

Tachometer/timer 21 power switch is ON, the

battery alarm function will operate after about

one more flight. When the meter pointer stops

at the boundary between the white and red

zones, recharge the battery.

26 Antenna

Strong 1m 10cm telescoping antenna. Extend

the antenna to its full height when using the

transmitter. The antenna will lock in place with

a click when pulled up to its full height.

Before using your

system, recharge the Nicd bat-

teries

as follows:

•Connect the DIN connector of the FBC-8B (2)

battery charger to the transmitter charging

socket 29. Also connect the 3P connector to

the airborne NR-4J Nicd battery and plug the

battery charger into a 120VAC outlet as shown

in Fig. 9. The airborne batteries can also be

charged through the DSC/CHG harness by con-

necting the CHG adaptor to the charger as

shown in Fig. 9. In this manner, the airborne

batteries can be charged without removing them

from the model.

•Normally recharge the battery for about 15

hours. If it has not been used for some time,

discharge and recharge it two or three times and

then charge it a full 15 hours.

• The amount of time remaining before the bat-

teries must be recharged can be estimated

using the Integrating Timer function of the

Tachometer/Timer

21. It

is recommended

that this function be used to monitor remain-

ing flying time. (See Page 12 for detailed

instructions.)

•The

Direct

Servo

Controller

system

connects

the signals from the transmitter directly to

terminal C of the receiver through a wire and

controls the

servos

without

radiating

radio-

waves. It is extremely convenient when flying

on the same band or during meets, etc.

• Make the connections shown in Fig. 9. Con-

necting the

special

DSC.CHG cord

with

tab

receiver terminal C and installing it to the

side

of the aircraft fuselage is very convenient.

•When the DIN connector of the DSC cord is

connected to the DSC connector 29, the

power to the encoder inside the transmitter is

turned on. The transmitter power switch is

OFF.

• When not using the DSC, disconnect the DIN

connector.

• To operate the servos, turn on the receiver

and servo switch.

can

be charged together or independently.

•A fully-charged transmitter battery can be used

for about 10 flights of 10 minutes each. The

airborne NR-4J Nicd battery can be used for

about 6 flights when 6 servos are used and about

4 flights when 10 servos are used.

• If the system is not to be used for some time, it

should be fully charged before storage and

recharged monthly to avoid full discharge and

loss of memory settings (ATV, FS, BFS memory,

etc.).

ADJUSTMENTS AND FLIGHT TECHNIQUES

•BASIC LINKAGES AND INSTALLATION

The FP-8SSAP has a servo reversing switch and ATV (Adjustable Travel Volume) for

each channel. Mount the servos without regard to their direction. Select and link servo

horns somewhat larger than those specified by the model manufacturer.

• Install the servos securely. Tighten the mounting

screws until the rubber grommets are slightly

compressed.

Note:

the

screws

are

too

tight,

the vibration dampening effect of the grommets

will be lost.

• Use extension cords as needed.

• It is suggested that a separate servo be used on

each aileron as this will allow use of the versatile

mixing and differential functions built into the

transmitter. Retractable landing gear can be

operated

with

single

servo

save

weight

with

two

servos

simplify

the

mechanical

link-

age as desired.

•Connect the pushrod to each servo horn, then

check to see if the direction of travel in relation

to stick movement is correct. If the direction of

travel is reversed, use the servo reversing switches

to correct.

• When installing the switch harness, cut a retangu-.

lar hole slightly larger that the full stroke of the

ON/OFF switch and install the switch so that it

operates smoothly. It is best to install the switch

inside the fuselage and attach a piece of wire to

the switch so that it can be operated from out-

side

the

aircraft. Locate the switch where

will

not be exposed to engine oil, dust, etc.

•Wrap the receiver in soft foam rubber. Water-

and dustproof the receiver by placing it in a

plastic bag and tying the mouth of the bag with

a rubber band. Do the same with the airborne

battery pack. Caution: The foam rubber should

be loosely wrapped and not compressed. This

will provide maximum protection from vibra-

tion.

• Use the rubber bands wrapped around the re-

ceiver to hold the servo and switch leads.

• Even though the receiver antenna may appear to

be too long, do not shorten it or fold it back.

• Be alert for possible electrical noise.

This system has noise rejection circuits, however

noiseless parts are recommended.

•Operate each servo to its full throw and check

for slop or binding in the linkage. Unreasonable

force applied to the servo horns can damage the

servo or horns and will greatly shorten battery

life. Adjust linkages and servo horns so that the

servos move smoothly even when the trim lever

and stick are operated simultaneously in the

same direction.

• After installation is complete, recheck each part,

then perform a range check by collapsing the

transmitter antenna and extending the receiver

antenna to its full length. Operate the transmit-

ter at a distance of 60 to 90 feet from the receiv-

er. The servos should operate normally at this

distance.

Normal 8 channel use (mixing and other functions not used).

ATV trimmers on aileron and elevator to the

desired deflection angles on the aircraft. The

deflection angle decreases when the 2ND ATV

trimmer is turned counterclockwise. Throttle con-

trol can be adjusted with the ATL trim lever 19 .

This completes the settings for basic 8 channel

use.

ADJUSTMENTS AND FLIGHT TECHNIQUES

•USING

ATV

(ADJUSTABLE

TRAVEL

VOLUME)

GENERAL - ATV (Adjustable Travel Volume)

allows independent adjustment of servo maximum

throw in each direction (without affecting the

neutral position). This is also sometimes referred

to as "separate endpoint adjustment". ATV is very

convenient when for example: a model requires

more DOWN elevator deflection than UP for equal

inside and outside loops (with equal control stick

deflection). Other aircraft may require slightly

different RIGHT or LEFT aileron or rudder

deflection to give equal response in each direction

(due to engine torque, precision of the model,

etc.). Two different ATV functions are possible

with this system. Memory (Pushbutton) ATV and

2ND

ATV.

MEMORY (PUSHBUTTON) ATV

This type of ATV is available on all eight channels.

Servo travel is adjusted as outlined in the example

below.

NOTE: Memory ATV settings are retained in the

transmitter memory circuit even when the power

switch is turned OFF. They are lost however, if

ADJUSTMENTS AND FLIGHT TECHNIQUES

•USING

DUAL

RATE

(AILERON, ELEVATOR, AND RUDDER)

Dual rate functions allow the flyer to alter the

maximum servo travel (and therefore control sensi-

tivity) during flight by using the appropriate rate

switch. At D/R OFF, servo deflection is maximum

in both directions (unless limited by ATV set-

tings). At D/R ON, servo deflection is reduced by

a percentage set with the D/R trimmers. Dual rate

adjustments always effect both directions of servo

travel.

AILERON DUAL RATE

• The aileron rate switch 14 has two D/R ON positions. Thus three different servo travel rates are available

on aileron. Rates can be adjusted to suit varying aircraft and maneuver requirements.

1 Aileron dual rate trimmer (I)

This trimmer sets the aileron travel when the aileron dual rate switch 14 is set

to the dual ON I position.

2 Aileron dual rate trimmer 2

(Switch in LINEAR Position)

Dual rate switch OFF

This trimmer sets the aileron travel

when the aileron dual rate switch

14 is set to the dual ON 2 posi-

tion.

Servo

throw

Trimmers [1] and [2] can adjust the

aileron travel from 40% to 80% of

the total travel.

When the dual rate switch is set to

ON, the servo throw can be set to

an arbitary angle smaller than

when the dual rate switch is OFF

(normal) as shown in Fig. 27. Use

the throw matched to the aircraft

and the maneuvers to be perform-

ed.

ADJUSTMENTS AND FLIGHT TECHNIQUES

•AUTOMATIC DUAL RATE ON RUDDER

• This function automatically switches rudder D/R to ON as the throttle lever is moved from LOW to HIGH

position. This allows a smaller rudder throw for precise inputs during rolling maneuvers (at HIGH throt-

tle) and increased throw (at LOW throttle) during stall turns, taxing,

etc.

new type

non-linear control response. It is similar to Ex-

ponential Control, but is easier to use. Aileron

will be used as an example.

•When the Aileron LINEAR/VTR Switch [3] is

in the LINEAR position, servo travel is linear

and directly proportional to the deflection of

the transmitter control stick as shown in Fig. 32.

In the VTR position (Ail. D/R Switch 14 must

also be in D/R OFF pos.), servo maximum throw

is unchanged. However servo tracking is the same

as when the rate switch is in the D/R 1, ON

position up to about 80% of the transmitter

stick deflection. Servo throw then abruptly in-

creases to the same deflection as when D/R

Switch 14 is in D/R OFF position. Fig. 32

shows the servo movement curve when VTR is

used. Another way to think of VTR is as "auto-

matic dual rate" that is switched off automati-

cally as the control stick is moved past the 80%

deflection point.

• Note: Maximum servo travel is the same in both

LINEAR and VTR modes and is determined by

ATV settings or maximum travel of the servo

itself if no ATV is set.

• If rate switches are set to D/R ON while in the

VTR mode, servo tracking will revert to LINEAR

and travel is set by the D/R trimmer.

•SUGGESTIONS ON ATV, D/R, AND VTR

POINTS TO REMEMBER (ATV, D/R. VTR)

• Servo maximum deflection is always determined

by ATV. If no ATV is set, maximum travel is

governed by the servo itself and is approximately

45 degrees in each direction from neutral.

•When Dual Rate is ON, servo travel in each

direction is reduced by the same percentage

(adjustable using D/R trimmers). For example,

in Fig. 33 one direction has been limited using

ATV. Both sides are reduced 20% when D/R is

ON. In other words, the ratio of UP to Down

will be maintained when D/R is ON or OFF.

• VTR operates only when D/R is set to OFF po-

sition (LINEAR/VTR switch must also be set to

VTR position).

•Servo tracking is always LINEAR when Dual

Rate is ON (regardless of LINEAR/VTR switch).

SUGGESTIONS

Fig.

• VTR is useful when different throw rates are

desired for different portions of the same ma-

neuver or when there may be insufficient time

between maneuvers for changing rate switches

manually such as in the FAI F3A or "Turn-

around" Pattern event.

•When preparing to test fly a new model, if you

are unsure as to the amount of Aileron deflec-

tion needed, set up as follows.

1 LINEAR/VTR switch [3] on LINEAR

2 Aileron D/R I at best estimate of desired

throw for normal flying or deflection speci-

fied on aircraft plans.

3 Aileron D/R 2 less movement than D/R (1)

4 D/R OFF set to provide somewhat more

throw than specified.

5 Set Ail. D/R Switch 14 to (1) position for

takeoff.

6 If aileron response is not comfortable, it can

easily be increased or decreased while air-

borne.

Try this set-up for AMA Pattern:

1 Aileron LINEAR/VTR Switch [U set to

LINEAR.

2 Adjust D/R (1) to give 3 rolls in approxi-

mately 5 seconds.

3 Use ATV to adjust for a fast roll rate when

D/R Switch 14 is OFF.

4 Adjust D/R 2 for slow roll (1 roll in 5

seconds).

Same as above except Aileron LINEAR/

VTR Switch [3] set to VTR position.

•USING ATL (ADJUSTABLE THROTTLE LIMIT)

HIGH

SLOW

The Throttle Trim Lever 19 affects the servo po-

sition only when the throttle control lever is in the

LOW (IDLE) position. HIGH throttle position

remains

unchanged. Adjustment

the

throttle

linkage is therefore very convenient.

1 Use a servo horn that allows slightly more

throw than needed.

2 Set the maximum opening at HIGH throttle

using Memory ATV (Page 17).

3 Use Memory ATV to set the extreme LOW

position to prevent servo binding when the

throttle barrel closes against the idle stop

screw.

4 With the engine running, use ATL Throttle

Trim Lever 19 to set the optimum idle

FS FUNCTION/HOLD FUNCTION

Fail Safe (FS) is a function which moves the servo

of each channel to a position preset (at the trans-

mitter) when an erroneous signal or continuous

strong noise is received for about 1 second or

longer. When the proper signal is lost or strong

interference received, the airborne system will

operate in the HOLD mode for about 1 second

before switching to the FS mode. When a normal

signal is received again for about 1 second, FS is

released and normal control resumes.

The HOLD functionstops all servos selected (by

button [47] at the position just before noise or

interference was received. When a normal signal is

resumed, HOLD is released.

A combination of FS and HOLD functions can be

selected on each channel at the modeler's discre-

tion.

FS, HOLD, and SERVO TEST functions are oper-

ated using three switches on the trimmer panel.

•AIRCRAFT WITH VARIABLE PITCH PROP

ADVANTAGES OF VARIABLE PITCH PROPELLEJB

The variable pitch propeller offers such advantages as:

1. The desired speed and pull can be adjusted.

2. Speed matched to the engine is obtained.

3. Low noise.

4. Air braking effect by

zero

pitch.

5. Idling is unnecessary.

Pitch control

servo

High pitch— —Low pitch

Matching of the variable pitch propeller to the digital proportional RC set is essential. Improper use is ex-

tremely dangerous. Therefore, read this section carefully.

Connect the pitch control servo to channel 8. A variable pitch propeller can be adequately controlled by a

common servo. Handle the servo the same as any other servo.

Install the servo and linkage as specified by the manufacturer. (Note) This section explains how to use a

MK variable pitch propeller.

Set switch [7] to the ACT

position.

Turn trimmers [4]

and

[5] fully counterclock-

wise.

Since trimmer'6 ] is adjusted

after making a test flight,

set

it to about the center.

Switch II is the mixing ON-

OFF switch. When it is set to

the OFF position, monitor

lamp 22 (B) comes on. When

it is set to the ON position,

the lamp goes out. Set the

switch to the ON position

and check the pitch control

(channel 8) servo stroke and

direction. Set the servo so

the propeller is pitched when

the throttle stick is set to

HIGH and is zero pitch when

the throttle stick is set to

LOW. If the servo turns in

the wrong direction, reverse

the setting of servo reversing

switch [57].

Fig.

Next, adjust the servo stroke. First set the trans-

mitter pitch control lever 8 to the HIGH posi-

tion.

Then adjust

the

pitch control

stroke

with the ATV trimmers 48 and 49 so a load is not

applied to the linkage. Set the mixing throttle po-

sition is 1 stop from the SLOW position (Fig. 41)

with the THROT POSIT trimmer

[8].

and check

if:

* The pitch is zero (minimum) when the throttle

lever is set to minimum slow.

* The pitch becomes 11 (maximum) when the

throttle lever is raised one stop.

Next, adjust the transmitter upper side pitch con-

trol

Set

the

throt-

tle lever to the HIGH side before making this

Since

with

pitch 11 (maximum) the propeller pitch when this

lever is set to the lowest position must be checked.

A variable pitch propeller is difficult to measure

with a pitch gauge. Therefore, adjust trimmer [6]

for a pitch somewhat lower than the maximum

pitch 11 ].

ADJUSTMENTS AND FLIGHT TECHNIQUES

Pitch 8-9

Pitch 11

(maximum)

Fig.

NOTE:

When lowering lever 8 , be careful that the pitch

does not go negative. This is adjusted during flight.

For example, flight is affected by the temperature,

air pressure, wind, and other conditions. Use this

lever adjusting the speed, pull, etc. to your liking.

Also select the engine tone quality by adjusting

the propeller pitch. Make quiet flights by fine ad-

justing the propeller pitch.

Next, adjust the throttle. First, set switch II to

the OFF position. Adjust the engine idling speed

to 2,200~2,500 rpm with the throttle trim lever

9 . Then set switch II to the ON position and

set the throttle lever to the maximum slow (zero

pitch) position. Adjust idle up lever 9 for an

engine speed of 3000 ~ 4000 rpm. Lever 9 is

inoperative when switch II is in the OFF posi-

tion. Use the variable pitch propeller as an air

brake during dives.

Fig.

Pitch zero does not have an air braking affect. If

the engine is running at a speed of 3000 ~ 4000

rpm, the air braking effect will not appear if the

propeller diameter is too small.

Adjust the throttle so the pitch is positive and the

engine idles when switch II is set to the OFF

position. Since lever 8 is also operative in this

state, optimum pitch adjustment is possible.

Operation when switch

9 Idle up lever

NOTES:

• The pitch always becomes maximum when the

throttle switch is set to HIGH.

• The speed cannot be increased with the idle up

lever 9 when the propeller pitch is zero.

• Since the air braking effect is higher than normal

when landing at zero propeller pitch, be careful

until you become familiar with the setting.

• Best result is often obtained by making the

tuned pipe longer.

VARIABLE PITCH PROPELLER AND ENGINE

POWER MATCHING IS ESSENTIAL FOR MAXIMUM PERFORMANCE

If the throttle stick is operated quickly during

flight, the engine will make an abnormal sound

(sputter). If the engine sound remains unnatural,

the pitch control or throttle servo operation tim-

ing can be delayed.

When the throttle lever is suddenly moved from a

high speed to a low speed, the throttle operates

before the propeller pitch changes to zero. If the

throttle lever is moved from HIGH to SLOW, the

pitch will change before the throttle operates.

Set the throttle delay time with trimmer [4] and

the pitch delay time with trimmer [5]. This

provides the same feeling as fixed propeller aircraft

and allows natural flight.

V.TAIL (ELEVATOR + RUDDER)

• This mixing is used for gliders,

scale model

Bonanzas, and other V-Tail aircraft.

• Install and connect the servos as shown in Fig.

67. Always connect the servo to the Right Rud-

dervator to CH2 (Elevator).

• Set Switches [16] and [17] as shown in Fig. 68.

Connect to

channel 4 (rudder).

Connect to

channel 2 (elevator).

Used channel 2 (elevator) for the right rudder.

When connecting the linkage, connect channel 2

(aileron servo) to the right wing rudder.

ADJUSTMENTS AND FLIGHT TECHNIQUES

INDEPENDENT AILERON DIFFERENTIAL OPERATION

• Adjustment of the Aileron Differential can help

reduce sideslip in turns and eliminate unwanted

Yaw movements in rolling maneuvers.

• Install and connect the servos as shown in Fig.

71. Always connect the Right Aileron servo to

CH1 (Aileron). The Left Aileron servo is con-

nected to CH7.

• Set Switches 16

and 17 as shown in Fig. 70.

• The Aileron DOWN deflection can be adjusted

by using trimmer 15 .

• The differential amount increases as trimmer 15

is turned clockwise. The differential is zero when

trimmer 15 is turned fully counterclockwise.

This is the same as ordinary aileron differential

operation, except that the ELEVN down amount

can be adjusted with this trimmer.

(One aileron servo mounted at

the right and at the left)

Fig.

The down amount can be ad-

justed with trimmer 15.

Connect to

receiver channel 7.

Connect to

receiver channel 1

* When connecting the linkage, connect channel 1

to the right wing aileron servo.

•

During

level

flight, smooth left turns

without

any sideslip can be made by increasing the right

wing aileron deflection angle without increasing

the left wing aileron deflection angle by turning

the aileron differential function. Smooth

right turns can be made by performing the op-

posite operation. Use this differential function

to reduce the aileron down angle rather than the

up angle.

V.TAIL AND FLPRON MIXING

•This combination of mixing functions can be

used with V-Tail gliders and other aircraft with

full

ailerons.

• Set

Switches

and

shown

• See FLPRON and V-TAIL sections (Page 34, 35)

for complete instructions on each of these func-

tions.

V.TAIL AND INDEPENDENT DIFFERENTIAL OPERATION

• This combination can be used aircraft with V-

Tail and full ailerons.

• Set Switches 16 and [17] as shown in Fig. 74.

• Adjust Aileron differential with Trimmer [15].

•See the V.TAIL and aileron differential sections

for a description of the linkages.

•SPLINED HORNS

This horn permits shifting of the

servo neutral position at the servo

horn. Setting and shifting the

neutral position

a) Angle divisions

Fig. 81

1) The splined horn has 25 seg-

ments. The amount of change per

segment is; 360: 25=14.4°

The minimum adjustable angle

determined by the number of

arms or number of the holes. For

four arms, the minimum adjustable

angle is:

b) Effect

Baseline A

Fig.

To shift the holes center line to

the right (clockwise) relative to

baseline A, shift arm 2 to the po-

sition of arm 1 and set it to the

position closest to baseline A.

(Example] For a four arm horn,

the angular shift per segment is

14.4°. The shift to the right is 90°

(14.4 x6)

3.6°

To shift by the same angle in the

opposite direction, use the oppo-

site arm number.

Fig.

For

a six arm horn, turn the arm

counterclockwise and set arm 2

to the position of arm 1. The ad-

justable angle is 60° — (14.4 x 4)

=2.4°.

Arm 3 shift 4.8° to the right, arm

6 shifts 2.4° to the left,and arm 4

shifts 7.2° to the right and left.

Digital

Proportional

Frequencies

(FOR

U.S.A.)

•The frequency of Futaba digital proportional

sets

can be changed among

bands

(1)~(6)

the 27MHz band only.

•However, a 27MHz band set cannot be changed

to 72MHz band, and vice versa.

•Therefore, always attach the correct frequency

flag to the end of the transmitter antenna.

Each frequency band has its own designated

color, as stated above. The frequency flag is

intended for identification purposes.

•Also change the frequency flag when frequency

is changed.

•Futaba paired crystals are precisely matched.

Always use a Futaba crystal set (transmitter,

receiver) when changing the frequency.

•It is illegal to change crystals of transmitter on

the 72-75MHz bands in the U.S.A.
