If this relatively simply variant should prove
impossible for whichever reasons, then the
alternative is a solution with two free mixers – and
potentially involving the »
Mix only channel «
menu, page 205.
In either case, however, the airbrake travels must
then be fi ne-tuned on the »
Servo adjustment «
menu, page 102.

Earlier, we discussed the problems with the butterfl y
(crow) confi guration. Namely: that with the use of
aileron differential, the aileron effect can be strongly
(negatively) affected by the aileron elevation. This is
fi rstly because further defl ection of the one aileron
upwards is (almost) no longer possible and secondly
because the downward-defl ected aileron – depending
on the elevation and degree of differential
confi gured – is often unable to achieve even its
"normal" position.
To be able to restore the effect of the aileron altered
in this way as far as possible, you should ensure
that you make use of the automated "Differential
reduction" feature. This feature continuously reduces
the degree of aileron differential as the airbrake
system is extended. The feature is confi gurable and
can even be set to suppress differential entirely.
A value of 0 % means that the "aileron differential" set
at the transmitter remains fully in force. An entry that
equals the % value set for aileron differential means
the differential is fully eliminated once the butterfl y
function is at maximum travel, i.e. with fl aps fully
extended. Setting a reduction value greater than the
aileron differential confi gured will eliminate the latter
even before the full travel of the airbrake joystick.
Values can be set in the range 0 to 150 %.
A simultaneous tap on the
cd
or
ef
keys of the
right touch pad ( CLEAR ) will reset a changed value
in a given active (inverse video) fi eld back to 0 %.

If the airbrake control – to be set to 1, 7, 8 or 9 on the
"Brake Offset" line of the »
Model type « menu, page
95 – is used to extend the fl aps as described previously
for the "Brake settings" menu, this will often have a
negative effect on the aircraft model's airspeed. This
mixer can be used to compensate this type of effect by
applying a corrective value to the elevator.
A brief tap on the center
SET key of the right touch
pad will switch to the display screen shown below:

The offset set in the » Model type « menu, page 94,
affects this mixer.
The vertical line on the display that indicates the
position of the airbrake control only moves from
the edge of the graph when the confi gured offset
is exceeded. In doing so, airbrake control travel is
automatically expanded back to 100 %, as described
in the »
Model type « menu.
Accordingly, the mixer's neutral point always lies on
the left edge, independently of the offset confi gured.
Now adjust the elevator curve in the direction of the
opposite end-point in accordance with requirements.
Note that this method for setting the 5-point curve
mixer follows the same principles that are applicable
to the curve mixers, already described on page 128 in
the context of the »
Channel 1 curve « menu.
