… will show you that control 7 is assigned to input 12.

This input serves as the throttle limiter. It acts sole-

ly on output “6”, to which the throttle servo is connec-

ted. The slider, which is connected as standard to the

CH7 socket on the transmitter circuit board, is assig-

ned to the throttle limiter.

Just to remind you:

The throttle limiter does not control the throttle servo;

it just restricts the travel of this servo in the forward

direction, in accordance with the setting you select.

The throttle servo is usually controlled by the collecti-

ve pitch stick via the throttle curve you have program-

med. For more details of these functions please read

the sections on pages 62 and 92 of the manual.

Select the ASY ﬁ eld in the “Travel” column, and incre-

ase the value in the inverse ﬁ eld from 100% to 125%,

with the throttle limiter pushed fully forward.

This ensures that the throttle limiter cannot possibly

restrict the full throttle travel set by the collective pitch

stick when the model is in ﬂ ight.

An additional transmitter control needs to be activated

in the menu ...

»Auxiliary switch« (page 75)

Even if you are a beginner to ﬂ ying and are not yet

ready for this, it is advisable at least to deﬁ ne the

auto-rotation switch, so that you have an “emergency

off” switch for the motor.

This is carried out in the sub-menu “Auto-rotation”:

press the rotary control brieﬂ y and move one of the

ON / OFF switches (e.g. two-position switch, Order

No. 4160) to the “ON” setting. On the right the switch

number (in our example “2”) appears, and this num-

ber will also identify the switch in the »Switch dis-

play« menu.

The AR switch should be located at a position on the

transmitter where you can easily reach it without let-

ting go of either stick, e.g. above the collective pitch

stick.

Note:

Please refer to the next page for more details on set-

ting up this “Emergency off switch”.

And another tip:

We recommend that you make it a routine matter to

assign all the switches a common “on” direction; then

a quick glance at the transmitter before ﬂ ying will

soon reassure you that all switches are “off”.

If you wish, you could at this point move to other sub-

menus and assign ﬂ ight phase switches, but our

simple programming example does not include such

reﬁ nements.

You have now completed the basic settings at the

transmitter, i.e. the procedure which you will need to

use time and again when setting up new models.

The actual set-up for your speciﬁ c helicopter is car-

ried out primarily in the menu ...

»Helicopter mixers« (page 90)

… where you will see the “Pitch” function in the very

ﬁ rst line; a brief press on the rotary control will take

you to the corresponding sub-menu. Here you will ﬁ nd

a graph of the collective pitch curve, which is initially

deﬁ ned only by the three reference points “L” (low), “1”

and “H” (high); in most cases this will be all you need.

Tip:

We strongly advise that you initially set up your heli-

copter using just these three reference points; more

points complicate the whole business, and at present

are likely to be more trouble than they are worth.

The reference point for hovering should generally be

the mechanical centre point of the collective pitch

stick, as this position feels completely natural to most

pilots. You can, of course, set up the curve to loca-

te the hover at a different point, but please don’t be

tempted to do this unless you know exactly what you

are doing. Start by setting the collective pitch stick

to centre. Assuming that you previously adjusted the

servos in accordance with the manufacturer’s instruc-

tions, the servo output arms will now (usually) be at

right-angles to the servo case. If you have not already
