… a same-sense "cc" and an opposite-sense "c
d" control function, although they permit any channel
to be used and offer differential travel for the opposing
function.
Note:
The symbols "cc " and " cd" indicate that the
corresponding inputs act upon the two servos coupled
by the mixer in the same and opposed directions
respectively – they do not indicate the servos' direction
of rotation! Accordingly, if wing fl aps are defl ected in
the wrong direction, simply swap the two inputs around
or use the servo reverse function from the "Servo
adjustments" menu; see page 90.
In the software, the V-tail mixer already mentioned is
supplemented by other "dual mixers" for the two aileron
servos at receiver outputs 2 and 5 and for the fl ap pairs
at outputs 6 and 7 (and 9 and 10 plus 11 and 12, if
present). 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 example on page 255):

Depending on activation, both servos operate either as
elevators or rudders. Differential travel is effective only
when a rudder command is given, in accordance with
dual mixer assignment. In this case
, both associated
trim levers 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.
Example:
Model with two rudders, with differential travel and
outward movement (e. g. swept-back fl ying wing):

When a rudder command is given, the second servo
connected to output 8 follows suit. (With this type of
programming, differential travel can be confi gured for
the rudders.) In this case, too, trim from the rudder stick
