Since the carburettor 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 con-
trol characteristics of the throttle / airbrake stick,
regardless of whether this control function affects the
servo connected to control channel 1 directly or af-
fects multiple servos via various mixers.
If flight phases have been specified in the »Phase
settings« and »Phase assignment« menus (see
pages 154 and 160) this option can be adapted on
a flight-phase basis. The given flight phase name,
e. g. «normal», will be shown at the bottom left of
the screen.
The control curve can be defined by up to 8 points
(termed "reference points" below) placed anywhere
along the path of stick travel. While the on-screen
graph considerably simplifies 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
stick travel ("L", low = -100 % travel) and the top end
of stick travel ("H", high = +100 % travel) – define a
linear characteristic curve.
First, switch to your chosen flight phase, if necessary.
Setting reference points
By moving the transmitter control (throttle/airbrake
stick), you can reposition the vertical line in the graph
between the two end-points "L" and "H". The current
stick 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 stick 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 be-
tween the two end-points "L" and "H", although the
distance between neighboring reference points must
not be less than approx. 25 %.
Move the stick. If a question mark can be seen in the
"Point" frame, then the next reference point can be set
with a tap on the centre SET key of the right touch pad.
Simultaneously, the "?" is replaced by a number and
the value field to the right of the reference point num-
ber 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 continu-
ously 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 stick to move the vertical line into the vicinity
of the reference point in question.
