Since the carburetor response or the effect of the
airbrakes or spoilers is often non-linear, you can make
compensatory adjustments to these in this menu.
The menu therefore enables you to change the
control characteristics of the throttle / airbrake
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.
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 (throttle/airbrake
joystick), 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) 6
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 corresponding
value on the "Point" line are displayed in inverse
video, see fi gure above, these can be erased with a
simultaneous tap on the
cd
or
ef
keys of the right
touch pad ( CLEAR ). 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. The reference point value displayed in
inverse video can be changed in a range of -125 % to
+125 % without infl uencing the neighboring reference
points.
