If you switch from this graphic to the autorotation
phase for testing purposes, the following appears
instead of the accustomed representation:
C1 Throttle

Autorot
That means that this mixer is switched off and the
throttle servo is switched to a fi xed value, which can
be adjusted as follows:
Return to the menu list with a tap on the
long as you are still in the autorotation phase, new
sub-menus are listed; specifi cally:
Pitch
Throttle position AR
Tail rot. offset AR
Gyro suppression

The line "Thr. setting AR" is important. Enter the value
to the right, depending on servo direction, to either
approximately +125 % or -125 %.

In doing so, the motor is safely switched off in the
autorotation phase (in case of emergency). Later,
when you have gained enough experience to practice
the autorotation fl ight, a more stable idle can be
entered here.
Adjustment notice for electric helicopters:
Since the motor must also be shut off for electrically
powered helicopters in case of an emergency, this
setting is adopted without change.
The further sub-menus are not important at the
moment. By switching off "autorotation", it returns to
the fi rst menu list.
Select the "Channel 1  Tail rot." settings page
in order to set static torque compensation for the

three interpolation points; everything else is reserved
for the experienced pilot. Do this by changing the
heading-lock systems from their intended uniform
pre-setting of 0 % at point "L" (minimum pitch) to
–90%
-30 % and at the opposite end, at point "H" to +30 %
(maximum pitch). These values may have to be

corrected in fl ight. It may also be necessary to set

If, contrary to the default setting, the gyro has a
transmitter-side sensitivity setting, another free
proportional control will be needed. This can be
assigned in the ...

... menu to "Gyr7" input. Activate the control
assignment with a brief tap on the center
the right touch pad then move the selected control
until its control number appears in the display:

Conclude this entry with a brief tap on the
the left touch pad then change to the column "- travel
+" with the  selection key of the left or right touch
pad. After a tap on the center SET
touch pad, the gyro's maximum sensitivity can be set
in the value fi eld displayed in inverse video, e.g. to
50 %. To this end, move the selected control into its
middle position or, if applicable also to the side, such
that only one value fi eld is displayed in inverse video:
I5 GL fr --- 0% +111%
Thr6 GL fr --- 0% +100%
Gyr7 GL Sl1 --- 0% +50%
I8 GL fr --- 0% +100%

This produces a fi xed value for as long as the control
remains at the right limit position. The correct value
must be adjusted in fl ight.
