four-way button and use the selection keys on
the left or right four-way button to set a value that
moves the aileron upwards as far as possible to
brake the model or, if you are using airbrakes as
the main braking system, the aileron should be set
to elevate only minimally to provide an extra brak-
ing effect.
Note:
To reliably prevent the servos mechanically strik-
ing their end-stops – which draws a heavy cur-
rent – you can set an appropriate limit value in the
column labeled "– limit +" in the »Servo adjust-
ment« menu, page 112.

... then finally, moving to the "D.red" line, set a %
value there which is greater than or equal to that
value set (or to be set) in the "Aileron differential"
line of the display screen "before" this one.
In this way, you can suppress the aileron differ-
ential when braking, thus ensuring that you can
count on sufficient aileron response despite your
ailerons being deflected upwards.

If required, i. e. if you have the feeling that you will
need to set pitch trim compensation when the flaps
and/or airbrakes are extended, you can program an
appropriate automatic mixer affecting the elevator at
this point.

The adjustment range of ±100 % makes it possible to
set the correct direction of differential, regardless of
the direction of rotation of the aileron servos. While
"0 %" corresponds to a normal linkage, i. e. no trans-
mitter-side differential, "-100 %" or "+100 %" repre-
sents the "split" function.
For aerobatic flying, low absolute values are required
to ensure the model rotates exactly along its longitu-
dinal axis when an aileron command is given. Values
near to the center (-50 % or +50 %) are typical for
facilitating turns in thermals. The split setting (-100 %,
+100 %) is popular with slope fliers, where ailerons
alone are often used for turning the model.

Here, you can set the degree to which the rudder
follows commands acting on ailerons. This is used
in particular in connection with aileron differential to
suppress adverse yaw and thus make it easier to fly
"clean" curves. You can of course still issue separate
commands to the rudder.
The adjustment range of ±150 % lets you set the
direction of deflection as appropriate. Optionally, this
mixer can be activated and deactivated with one of
the switches that is not self-restoring or a control
switch so the mo del can be controlled with only the
ailerons or rudder if desired.
Typically, this mixer is set so that the rudder is deflec-
ted to the same side as the upward-oriented aileron,
and you will find that setting a value of around 50 % is
usually highly appropriate.
Settings are always made symmetrically relative to
the neutral point of the aileron stick.
A simultaneous tap on the or keys of the
right four-way button (CLEAR) will reset a changed
value in a given active (inverse video) field back to
0 %.
