Notice:
A rotor adjustment gauge, such as the Graupner
adjustment gauge, Order No. 61 is very useful in reading
the angle.
Now move the pitch joystick toward the pitch minimum
position until its limit position. Depending on the ability
of the pilot, adjust the value of point "L" so that the blade
angle of approach is 0 to -4 °. Now a slightly pitched line
arises at the hovering points, the so-called pitch curve,
which can appear as follows:
Pitch

Input –100%
Output –75%
Point L –75%

Now you can, if you like, move the marking frame
upward with the arrow keys to the "Curve" line and after
activation of the value fi eld by briefl y pressing the central
SET key of the right touch pad, set the curve function of
the mixer to "on".

If you now switch to autorotation phase – at the bottom
left of the display the fl ight phase name "Autorot"
appears – the "old" pitch curve is again:

Now carry out the same setting as before in the normal
phase. Only at point "H" – at pitch maximum – the pitch
angle can be increased by approximately 2 °. In doing
so, you will have somewhat more of an angle to catch
the model later on (1).
After setting the pitch curve, move the autorotation
switch back and return to the helicopter mixer menu
selection by briefl y pressing the central ESC
left touch pad. From there, switch to the line
"C1 Thro" in order to adjust the throttle curve.
First the adjustment range of the idle trim must be
adjusted with the throttle curve. For this purpose, move
the pitch joystick to its minimum position and then set
point "L' to approximately -65 %.

With the throttle limiter closed and the idle trim
completely open, move the pitch joystick 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 throttle curve. The further settings along the throttle
curve must be carried out later in fl ight.
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
key of the
throttle servo is switched to a fi xed value, which can be
adjusted as follows:
Return to the menu list by pressing ESC. As long as you
are still in the autorotation phase, new submenus are
listed; specifi cally:
