If you now switch to autorotation phase – at the bot-
tom left of the display the flight phase name "Autorot"
appears – the "old" pitch curve is again:

Now carry out the same setting as before in the nor-
mal phase. Only at point "H“ – at maximum pitch – is it
possible to increase pitch angle by about 2 °. In doing
so, you will have somewhat more of an angle to catch
the model later on (!).
After setting pitch curve, move the autorotation switch
back then return to the helicopter mixer menu selec-
tion with a brief tap on the centre ESC key of the left
touch pad. In that display, change to the "Channel 1
Throttle" line to set the throttle curve.
The adjustment range for idle trim must first be
matched to the throttle curve. Do this by putting the
pitch stick into its minimum position then set point "L"
to about +15 %:

With the throttle limiter closed and idle trim completely
open, move the pitch stick back and forth somewhat at
the minimum limit position. The throttle servo may not
move with it in the process. No you have established
a seamless transition from the idle trim to the throt-
tle curve. The further settings along the throttle curve
must be carried out later in flight.
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 fixed value, which can
be adjusted as follows:
Return to the menu list with a tap on the ESC key. As
long as you are still in the autorotation phase, new
sub-menus are listed; specifically:
Pitch
–100%
Tail rot. offset AR
0%
Throttle position AR
Gyro suppression
0%
Gyro offset 0%
SEL
Autorot
The line "Thr. setting AR" is important. Enter the value
to the right, depending on servo direction, to either
approximately +125 % or -125 %.
Pitch

In doing so, the motor is safely switched off in the au-
torotation phase (in case of emergency). Later, when
you have gained enough experience to practice the
autorotation flight, 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 to adopted without
change.
The further sub-menus are not important at the mo-
ment. By switching off "autorotation", it returns to the
first menu list.
Select the "Channel 1 Tail rot." settings page
in order to set static torque compensation for the
tail rotor. In this case, also work with a maximum of
three interpolation points; everything else is reserved
for the experienced pilot. Do this by changing the
heading-lock systems from their intended uniform
