… a same-sense "cc" and an opposite-sense
"cd" control function, although they permit any
channel to be used and offer differential travel for the
opposing function.
Important notice:
Since the same and opposite sense infl uences
of the given input on the two servos or rudder
fl aps – coupled to one another by the dual mixer – are
determined by, among other things, their installation
situation and the direction of rotation specifi ed in
the »Servo adjustment« menu, the symbols "cc"
and "cd" are to be perceived more as synonyms
rather than as consistently appropriate defi nitions!
Accordingly, if wing fl aps are defl ected in the wrong
direction, simply swap the two inputs or use the
"servo reverse" option in the »Servo adjustment«
menu; see page 102.
In the software, the V-tail mixer already mentioned is
supplemented by other "dual mixers" for realization
of the two aileron servos on receiver outputs 2 and
5 and for the fl ap pairs on outputs 6 and 7, possibly
also 9 and 10. These are activated via the aileron
stick and the transmitter control that has been
assigned to input "6" on the »Control adjust« menu.
In the same way, the four freely-programmable
dual mixers on this menu can be used to couple
two further control functions, a feature that would
otherwise only be possible with time-consuming
programming of free mixers.
Here, we will use a "V-tail with rudder differential" as
our example to explain the programming of a dual
mixer (see also the examples on page 286):

Depending on activation, both servos move in the
sense of elevators or rudder fl aps. The differentiation,
according to dual mixer confi guration, is only effective
for rudder activation. In this case, both corresponding
trim wheels are effective. No additional free mixers
are required for this arrangement. When using this
mixer, however, the tail type MUST be entered as
"normal" on the "Model type" menu.
Tip:
All settings can be checked directly in the »Servo
display« menu, which can be accessed from almost
any other menu by simultaneously tapping the ef
keys on the left touch pad.
Example:
Model with two rudders, with differential travel and
outward movement (e.g. swept-back fl ying wing):
