Program description: transmitter control settings – model helicopter
Important:
In contrast to servo travel adjustments, changing the
transmitter travel setting affects all mixer and coupling
inputs derived from it, i. e. in the final analysis all the
servos which can be operated using the associated
transmitter control.

In principle all transmitter controls (rotary proportional
knob) and switches present on the transmitter can be
assigned to the individual inputs within the Helicopter
program.
However, please note that some inputs available in this
menu are already pre-defined for helicopter-specific
functions, and for this reason cannot be used without
restriction.
For example, the receiver sequence printed on page 65
shows that the throttle servo (or the speed controller of
an electric-powered model helicopter) must be con-
nected to receiver output “6”, i. e. control channel “6” is
reserved for motor speed control.
However, in contrast to a fixed-wing aircraft, the throt-
tle servo or speed controller is not directly controlled
by the throttle stick or any other transmitter control, but
via a complex mixer system - see “

menu, starting on page 114. The “throttle limit function”
(described on the next page) also has an influence on
this mixer system.
Assigning a transmitter control or switch in the “Throt-
tle” line, or its supplementary control signal, would only
unnecessarily “confuse” this complex mixer system.
For this reason the “Throttle” input MUST always
be left “free” when you are programming a model
helicopter.

If the gyro you are using features infinitely variable gain
control, then you can pre-set the static gyro effect by
setting an “offset” within the range +/-125%, separately
for each flight phase, in the “Gyro” line of the “

Once you have entered these pre-defined - static - gain

of the transmitter control this corresponds to the setting

trol in the “Gyro” line of this menu: in the centre position
of the transmitter control this corresponds to the setting
selected in the “
Helicopter mixers” menu (see section
starting on page 118). If the transmitter control is moved
from this centre point in the direction of full travel, gyro
gain is increased; towards the opposite end-point it is
reduced. This is a fast, simple method of fine-tuning gyro
gain when the model is in flight - perhaps to suit varying
weather conditions - or alternatively to find the optimum
setting. In software terms you can also limit the gain
range to both sides by restricting the transmitter control
travel.

notes provided with your gyro before carrying out
these adjustments, as you could render your heli-
copter uncontrollable if you make a mistake.
