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.
For detailed instructions on setting a curve mixer,
please refer to the »Channel 1 curve« menu option
text beginning page 134.

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 transmitter-
side differential, "-100 %" or "+100 %" represents the
"split" function.
For aerobatic flying, low absolute values are
required to ensure the model rotates exactly
along its longitudinal axis when an aileron
command is given. Values near to the centre (-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 di-
rection 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.

To provide support for the elevator for tight turns and
aerobatics, this mixer can be used to make the aileron
function follow controls sent to the elevator. The mixer
direction chosen must ensure that the ailerons are
deflected downwards when the elevator is oriented up-
wards and vice versa for a downward-oriented eleva-
tor – i. e. in opposite directions. This mixer can be made
optionally on/off switchable with one of the switches
that is not self-restoring or a control switch.
To configure symmetrical mixer values, move the eleva-
tor stick to its centre position, so that the marker frame
surrounds both value fields. To configure asymmetric
values, move the stick to the corresponding side.
