Unlike the "Channel 1 curve" menu, however, this 
display relates only to the control curve of the pitch 
servos: the "Channel 1 curve", on the other hand, affects 
all servos controlled via the throttle/collective pitch stick.
Note that the output signal of the "Channel 1 curve" 
option thus functions as an input signal for the 
collective pitch curve programmed here: In the 
graph, the vertical line is synchronized with the 
throttle/collective pitch stick and therefore follows 
the current Channel 1 curve characteristic.
The control curve can be defi ned (separately per fl ight 
phase) by up to 6 points, termed "reference points", 
placed at any point along the joystick travel.
Initially, however, fewer reference points are adequate 
for setting up the collective pitch curve. We recommend 
beginning with three reference points to start with. These 
three points – namely the two end-points "Pitch low (L)" 
(= -100% control travel) and "Pitch high (H)" (= +100% 
control travel) plus a point at the center of control travel 
still to be set – defi ne an initial linear profi le for the 
collective pitch curve.
Programming details
First, switch to your chosen fl ight phase, e. g. "Normal".
The throttle/collective pitch stick is used to move the 
vertical line in the graph between the two end-points 
"Point L" (minimum pitch at -100%) and "Point H" 
(maximum pitch at +100% control travel): at the same 
time, the current joystick position is shown numerically 
on the "Input" line (-100% to +100%). 
The point at which the vertical line crosses the curve is 
termed the "Output", and can be varied at the maximum 
of 6 reference points within the range -125% to +125%. 
A control signal modifi ed in this way affects only the 
collective pitch servos. 
In the example to the left, the joystick is at exactly 0% of 
control travel and also generates an output signal of 0%, 
since the characteristic curve is linear.
Up to 4 additional reference points can be set between 
the two end-points "L" and "H", although the distance 
between neighboring reference points must not be less 
than approx. 25%.
Setting reference points
If necessary, use the left or right arrow key 
 to drag 
the marker frame downwards, until it is at the "Point" 
line:

Move the joystick. If the display shows a framed 
question mark, then you can set the next reference point 
by tapping the center 
SET
 key on the right touch pad. 
Simultaneously, the "?" is replaced by its number and 
the value fi eld to the right of the reference point number

The order in which you generate the (maximum) 4 
reference points between the end-points "L" and "H" is 
irrelevant, since the reference points are continuously 
renumbered automatically from left to right as they are 
entered.
Confi guring reference points
To confi gure a point, use the joystick to move the vertical 
line onto the point you wish to change. The number 
and current curve value of this point are displayed on 
the left side of the display, on the "Point" line. Briefl y 
tap the center 
SET
 key on the right touch pad. Use the 
arrow keys on the right touch pad to change the current 
curve value shown in the highlighted fi eld. The possible 
range is -125% to +125% and changes do not affect 
neighboring reference points.
