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 center
ESC
touch pad. In that display, change to the "C1 Thro"
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 complete-
ly open, move the pitch stick back and forth some-
what 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 throttle curve. The further settings along the throt-
tle 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:

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
long as you are still in the autorotation phase, new
sub-menus are listed; specifically:

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 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 "C1 Tail" 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 pre-setting of 0 % at point

at point "H" to +30 % (maximum pitch). These values
may have to be corrected in flight. It may also be nec-
essary to set point "1" in the middle.

Now, for testing purposes, switch back to the auto-
rotation phase. Here the setting is also deactivated;
the tail servo no longer reacts to pitch movements
(no torque usually arises when the main rotor is not
powered). All additional interpolation points are not
currently of importance yet.
If, contrary to the default setting, the gyro has a
transmitter-side sensitivity setting, another free pro-
portional control will be needed. This can be assigned
