… 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.
Important notice:
Since the same and opposite sense
inuences of the given input on the two
servos or rudder aps – coupled to one
another by the dual mixer – are determined by,
among other things, their installation situation and the
direction of rotation specied in the »Servo
adjustment« menu , the symbols " " and " "
are to be perceived more as synonyms rather than as
consistently appropriate denitions! Accordingly, if
wing aps are deected in the wrong direction, simply
swap the two inputs or use the "servo reverse" option
in the »Servo adjustment« menu; see page 112.
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 flap 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 as-
signed 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 fur-
ther 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 306):
Use the Select buttons of the left or right-hand four-
way button to select the column you wish to access.
Press the central SET button of the right-hand touch
pad to activate the Value field, and then set the de-
sired value using the Select buttons:

In the dual mixers exemplified herein move both to re-
ceiver outputs 3 and 4 connected servos, depending
on the operation of the associated stick, as elevators
or rudder flaps. The differentiation is effective accord-
ing to the allocation in the dual mixers only rudder
control.
Depending on activation, both servos move in the
sense of elevators or rudder flaps.
