way button and enter a suitable value using the selec-
tion keys on the left or right four-way button. To ensure
a sufficiently strong braking effect, note that you should
try to lower the flap as low as is mechanically possible.
From the second line on this display screen, you can
switch to the sub-menu "Elevat curve" by briefly tap-

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.

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.
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 %.

To provide support for the elevator for tight turns and
aerobatics, this mixer can be used to make the flap
function follow controls sent to the elevator. The mixer
–––
direction chosen must ensure that the flaps are deflect-
–––
ed downwards when the elevator is oriented upwards
–––
and vice versa for a downward-oriented elevator – i. e.
in opposite directions. This mixer can be made option-
ally 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.
Values in the range -150 % to +150 % are possible, so
as to adjust the function to the direction of servo rota-
tion or direction of flap deflection.
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 %.
The "typical" values configured for this mixer
are single-digit or low two-digit values.

This mixer is used to set elevator (pitch-trim) compen-
sation when a flap command is given. This typically
enables you to adjust the model's airspeed automati-
cally when flaps are lowered.
If you have used the »Control adjust«, page 112, to
assign Input 6 to a transmitter control or switch then
this also affects this mixer.
To configure symmetrical mixer values, move the flap
control to its centre position, so that the marker frame
surrounds both value fields. To configure asymmetric
values, move the stick to the corresponding side.
