Note:
You can obtain a switching threshold of more than
+100% by temporarily increasing the travel of servo 1
to more than 100% in the “
Servo settings ” menu, then
returning it to the original value after storing the switch-
ing threshold.
In the right-hand column you can now assign a switch
which can be used (in an emergency) to cut the motor.
We recommend one of the two self-centring momentary
buttons SW 1 or 9:

In the “Rotor direction” line you enter the direction of
rotation of the main rotor using the arrow buttons of the
right-hand touch-key, after briefl y pressing the central
SET button:
“right”: the main rotor spins clockwise as viewed from
above.
“left”: the main rotor spins anti-clockwise as viewed
from above.
Simultaneously touching the
cd
or
ef
buttons of the
right-hand touch-key ( CLEAR ) switches to “right”.

The program requires this information in order to set up
the mixers to work in the correct “sense”; this applies to
the mixers which compensate for rotor torque and motor
power. You will fi nd these in the “
Helicopter mixer ”
menu:

default settings are -100% for the “Motor OFF” position
of the throttle servo and +150% for the throttle curve:

If you wish to change the default value of the throttle
servo’s “Motor OFF” position, briefl y press the central
SET button of the right-hand touch-key: the current
setting is highlighted. Now use the arrow buttons of the
right-hand touch-key to set a value at which the motor is
reliably “off”, but without stalling the servo. For example:
-125%:

The - high - default value in the centre column ensures
that the motor can be stopped over the maximum pos-
sible range of the throttle curve using the switch which
has yet to be assigned in the right-hand column.
However, if you want to set an individual threshold after
which it is possible to switch to the motor OFF position,
then move the throttle / collective pitch stick to the posi-
tion you desire, and briefl y press the central
SET button
of the right-hand touch-key:
