Since the carburetor response or the effect of 
collective pitch is often non-linear, you can make 
compensatory adjustments to these in this menu. 
The menu therefore enables modifi cation of the 
control characteristics of the motor/collective pitch 
joystick
, regardless of whether this control function 
affects the servo connected to control channel 1 
directly or affects multiple servos via various mixers.
If fl ight phases have been specifi ed in the »Phase
settings
« and »Phase assignment« menus (see 
pages 142 and 148) this option can be adapted on 
a fl ight-phase basis. The given fl ight phase name, 
e.g. «normal», will be shown at the bottom left of 
the screen.
The control curve can be defi ned by up to 8 points 
(termed "reference points" below) placed anywhere 
along the path of joystick travel. While the on-screen 
graph considerably simplifi es the process of setting 
and adjusting the reference points, we recommend 
that you set fewer reference points to begin with.
Please note that the curve characteristic you set 
here acts as the input signal for specifi c mixers in the 
»Helicopter mixer« menu, page 176.

In the basic software set-up, 2 reference points–
namely the end-points at the bottom end of joystick 
travel ("L", low = -100 % travel) and the top end of 
joystick travel ("H", high = +100 % travel)–defi ne a 
linear characteristic curve.
First, switch to your chosen fl ight phase, if necessary.
 Setting reference points
By moving the transmitter control (motor/collective 
pitch stick), you can reposition the vertical line in the 
graph between the two end-points "L" and "H". The 
current joystick position is also displayed in numerical 
form on the "Input" line (-100 % to +100 %). The point 
at which this line crosses the curve is termed the 
"Output", and can be varied at the reference points 
within the range -125 % to +125 %. The control signal 
altered in this way will then affect all subsequent 
mixer and coupling functions. 
In the example above, the joystick is at 0 % of control 
travel and also generates an output signal of 0 %, 
since the characteristic curve is linear.
Up to 6 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 %. 
Move the joystick. If a question mark can be seen in 
the "Point" frame, then the next reference point can be 
set with a tap on the center 
SET
 key of the right touch 
pad. Simultaneously, the "?" is replaced by a number 
and the value fi eld to the right of the reference point 
number will be shown in inverse video.

The order in which you generate the (maximum) 8 
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.
 Erasing reference points
To delete one of the reference points (1 to max. 6), use 
the joystick to move the vertical line into the vicinity 
of the reference point in question. As soon as the 
reference point number and its associated value is 
shown on the "Point" line (see screen image above), 
following activation of the value fi eld on the "Point" 
line now in inverse video with a simultaneous tap on 
the
cd or ef keys of the right touch pad (CLEAR) it 
can be erased. Complete the operation with a brief tap 
on the center key 
ESC
 of the left touch pad.
 Changing reference point values
Move the joystick into the range of the reference point 
that is to be changed: "L" (low), 1 … 6 or "H" (high). 
The number and current curve value of this point are 
displayed. Activate the value fi eld with a brief tap on 
the center 
SET
 key of the right touch pad. The point 
value fi eld is now highlighted and can be set within
