Differential aileron mixing
In order to use the Differential Function, flaperon or ele-
von (Delta), wing mixing must be selected in the Model
Set-Up Mode and two servos must be used to operate
the ailerons (one on each). In the Function Mode, use
the UP or DN key to select Differential Aileron Mixing
and access by pressing the UP and DN keys simulta-
nously.
Note:
The Differential Aileron Mixing Function will
only be shown in the Function Model if either
Flaperon or Delta wing types have been pre-
viously selected in the System Mode.

Programmable Mixing (1~4)
The mx-12 offers four programmable mixes to be used
for any number of different purposes. This function al-
lows mixing any one channel to any other channel. This
mix can remain on at all times or be switched on and off
in flight using a number of different switches.
Mix numbers 1-3 are of the standard variety, in that the
digital trim for the master channel only affect the master
channel, and not the slave channel. Mix number 4 is
of the “Trim Include“ variety. This mix is used any time
the mix requires the slave channels trim position to be
varied when the master channels digital trim position is
varied. An example for this type of mix would be when
dual elevator or dual aileron servos are used and con-
nected to two separate channels of the system, rather
than using a single channel with a Y-harness.
Each channel of this radio is identified by an abbre-
viated name. The chart below indicates the channel
and its corresponding abbreviation. The channel name
apperaing first is known as the “master channel“ or the
channel to which you want to mix. The second number
is known as the “slave channel“ or the channel that is
being mixed into the master channel. For example,
AIL
RUD would indicate aileron-to-rudder mixing.
Each time the aileron stick is moved, the aileron will
deflect, and the rudder will automatically move in the
direction and to the value input. Mixing is proportional,
so small inputs of the master channel will produce small
outputs of the slave channel. Each programmable mix
has a mixing “offset“. The purpose of the mixing offset is
to re-define the neutral position of the slave channel.
