… a same-sense "
 " and an opposite-sense " 
" control function, although they permit any channel 
to be used and offer differential travel for the opposing 
function.
Note:
The symbols "
  " and "  " 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
