For instance, if two channels are used for two rudders and a regu-
lar or multi-point mix is used to move the rudders in unison, it’s
important to activate Include Mixing to ensure that the Slaved
rudder channel always moves with the Master rudder. If the rud-
der stick is moved, both rudders will move, even if Include
Mixing is not active. However, the Slaved rudder will not move if
input is received from a source other than the rudder stick, such
as the snap roll button, or from another program mix, etc.
Another way to describe Include Mixing is that it will cause the
Slave channel to react to the Master channel at all times, regard-
less of where the input is initiated (stick, snap roll button, another
programmable mix, etc.). It can also result in using fewer mixes
in some instances.
An arrow will appear on the display to the left of the Master
channel when Include Mixing is activated.
To illustrate how Include Mix can result in using fewer mixes, see
the folowing example:
Mix1: AILE › THRO
Mix2: › THRO › RUDD
Mix2’s operating value includes the operating value from Mix1’s
Master channel (aileron). By moving the aileron control stick,
Mix1 has the ailerons mixing into the throttle. At the same time,
Mix2 is mixing throttle into the rudder. Since Include Mixing is
activated, you are also mixing your ailerons into the rudder. This
results in the aileron stick moving not only the aileron servo, but
also the throttle and rudder servos.
Include Mixing may sound complex, but it actually eliminates the
need for a third mixing program to mix aileron and rudder chan-
nels. Therefore, Include Mixing reduces the number of mixing
programs needed when using multiple mixing functions.

function from the Include Mixing function.
Origin Mixing
In order to understand Origin Mixing, it’s necessary to first
understand how Normal Mixing operates.
In Normal Mix, if the dual rate, exponential rate, VTR and/or
trace rate value of the Master channel is assigned, it also affects
the Slave channel. For example, if rudder is mixed to nose gear
steering (AUX 4) and an expo value is assigned to the rudder, the
nose wheel steering (AUX 4) will have the same expo value as
the rudder.
Now using the same example (RUDD to AUX 4), let’s turn on the
Origin Mix and see what effect it has.
With Origin Mix activated, D/R, Expo, VTR, or TR does not
affect the Slave channel (AUX 4). The Slave channel keys direct-
ly off of the original stick, ignoring the “modifiers” that have
been assigned to the Master. With Origin Mixing on, the rudder,
dual rate, expo, etc., will have no effect on the nose wheel steer-
ing.
There is one other very important feature associated with
Origin Mix. It is the ability to use a lever, switch, or knob to con-
trol other mixers, even when the lever, switch, or knob has been
inhibited in Function Select (Code 17) or has otherwise been
inhibited as the result of using a built-in function.
This is possible because Origin Mix instructs the transmitter to read
and act upon only the physical position of the lever, switch, or knob
(the control), and to disregard the channel that the control is normally
associated with. The manner in which the transmitter reacts to the
control is dependent upon what is set up in the program mixer.
This Origin Mix function can be demonstrated by a simple and
practical example involving the Flap lever located on the left side
of the transmitter and the Flaperon wing type that is typically
used to control ailerons with two servos on two channels. Our
example assumes that it is an aerobatic aircraft and as such, we
don’t need the ailerons to work as flaps—only as ailerons.
The factory default is to have the Flap lever assigned to the Flap
channel (AUX1/FLAP). When the Flap lever is moved, it causes
the Flap channel/servo to move. When we use the Flaperon wing
type to control the ailerons with two servos/channels, we plug the
left aileron into the Flap channel (AUX1/Flap). Since we don’t
want the ailerons to act as flaps, we Inhibit the Flap lever in
Function Select (Code 17). At this point, the Flap lever no longer
has any effect on the Flap channel—it has been
disconnected—when the lever is moved, nothing happens.
The Flap lever is now free to be used for other purposes. Let’s say
we want to use it for an idle-up, where the Flap lever is used to
increase the idle of our engine while flying, and then to reduce
the idle when it is time to land. We can accomplish this using a
program mixer; selecting the Flap channel (AUX1/FLAP) as the
Master; selecting the throttle channel as the Slave; and turning on
Origin Mix. If you are following along and wish to program this
idle-up to the Flap lever, do the following:
1. Inhibit the Flap lever in Function Select (Code 17) if it is not
already inhibited.
2. Access an unused program mixer (51–55).
3. Select Channel 6 (AUX1/FLAP) as the Master and select
Channel 1 (throttle) as the Slave.
4. Touch PAGE two times and select Origin Mixing, telling the
mixer to sense the Flap lever.
5. Touch PAGE again to get to the first mixer screen.
6. Move the Flap lever all of the way down.
7. Touch STORE to store the offset—this sets the mix starting point
to the lever’s lowest position so that the idle can only be increased
and not accidentally decreased, which might kill the engine.
8. Touch the + key until the value reaches 15%—this limits the
