Program description: wing mixers – fixed-wing model
flap

aile
(Flap  aileron)
This mixer causes a variable proportion of the flap signal
to be mixed in with the aileron channels 2 and 5 so that
the ailerons follow the movement of the flaps, albeit
normally with a smaller deflection.
The adjustment range is +/- 150%. For this mixer the
“usual” settings are around 50%.
Simultaneously pressing the
 or  buttons of the
right-hand touch-key ( CLEAR ) resets an altered value
to 0%.
Note:
If you assign a transmitter control to inputs 5 and 6 in
the “
Transmitter control settings
” menu for adjust-
ing the flap positions, then you should leave the value
for this mixer at 0%. See the notes on page 109 in this
regard.
diff red (Differential reduction)
The problem of reduced aileron response in the but-
terfly configuration has been mentioned earlier: if aileron
differential is employed, the aileron response on the
landing approach may be adversely affected through
the extreme “up” deflection of the ailerons, permitting
virtually no further up-movement; on the other hand
the “down” travel has already been reduced by the
programmed differential setting. The overall result is
significantly reduced aileron response compared with
the normal setting of the control surfaces.
In this case you really should use “differential reduc-
tion” if at all possible. This reduces the degree of aileron
differential when you invoke the butterfly setting using
the airbrake stick. Differential is reduced progressively,
or even eliminated altogether, as the airbrake stick is
moved towards its end-point.
A value of 0% at this point means that the full pro-
grammed aileron differential is retained. A value of 100%
means that the aileron differential is completely elimi-
nated at the
maximum butterfly setting, i. e. when the
airbrakes and other glide path control surfaces are fully
extended. If you set a value above 100%, the aileron
differential is eliminated even before full travel of the
airbrake stick is reached.
The adjustment range is 0 to 150%.
Simultaneously pressing the

or

buttons of the
right-hand touch-key ( CLEAR ) resets an altered value
to 0%.
