Rounding off the Channel 1 curve
In the following example the reference points have
been set as follows, as described in the last section:
Reference point value 1 to +50%,
Reference point value 2 to +90%, and
Reference point value 3 to +0%.
C h a n n e l 1 C U R V E
I n p u t + 0 %
C u r v e O u t p u t + 9 0 %
o f f P o i n t 2
+ 9 0 %

This “jagged” curve profi le can be rounded off auto-
matically simply by pressing a button. Press the EN-
TER button next to the “curve symbol” :
C h a n n e l 1 C U R V E
I n p u t + 0 %
C u r v e O u t p u t + 9 0 %
o n P o i n t 2
+ 9 0 %

Note:
The curves shown here are only for demonstration
purposes, and by no means represent realistic thrott-
le / airbrake curves.
“Real world” examples of this application can be
found in the programming examples on pages 125
and 147.
Example: reversing a transmitter control
To reverse the direction of a transmitter control, e.g.
to operate airbrakes, so that the airbrakes are retrac-
ted when the stick is “back” (towards you) and exten-
ded in the “forward” position, you simply need to pro-
duce the “mirror-image” of the Channel 1 curve. Raise
point “L” to +100% and lower point “H” to -100%. The
following example shows how to reverse a simple li-
near control curve:
C h a n n e l 1 C U R V E
I n p u t - 6 0 %
C u r v e O u t p u t - 6 0 %

Of course, the direction of the Ch1 control can also
be reversed in the »Model type« menu by pre-set-
ting the “throttle minimum position”. In this case the
direction of effect of the Ch1 trim is also reversed; see
page 52.
