Control Mix
· Example: "Overwrite" transmitter control mixer mode:
The throttle and landing functions (spoiler) are to be
controlled by one stick, according to flight phase:
Function in the Landing flight phase:
Throttle is controlled by the roller,
the spoiler function with the stick.
Function in the Launch and Normal flight phases:

Throttle is controlled exclusively using the stick.
Caution!: for safety reasons it is essential to remove
the propeller before continuing with the programming
procedure.
· Set up a new model using the "Glider" model type, with
active flight phases.
· Assign the transmitter controls in such a way that the
spoiler function is on the stick, and throttle is on the roller.
· The next step is to program the model completely, with
separate Throttle / Spoiler functions, right through to the
end.
· Ensure that all the mixers have a Spoiler input in the
Landing phase only.
Servo mix
Using the 4 servo mixers, operating elements or even mixers
can be mixed directly on servos.
All "inputs" whose names end with "+" are mixers (e.g. ele-
vator+); all remaining inputs are operating elements.
The outputs are always servos; they are displayed with
position numbers on the receiver and the corresponding
function.
Example: Servo mix - "Mix" mode:
With a dual-motor plane, the motor on the outside of the
curve is to be additionally accelerated during curve flight to
support the effect of the rudder.
· To do this, assign the "Throttle+" function to a second chan-
nel (e.g. 7 Throttle+) in the servo menu under "servo as-
signment". Check that both regulators are working properly.
· Create a servo mixer for the left motor, set the three-point-
curve so that the throttle is increased slightly when con-
trolling the rudder to the right, as shown in the following
image.

Creating the transmitter control mixer required:
The purpose of the mixing arrangement is to ensure that
throttle is controlled by the stick in all flight phases with the
exception of the Landing phase.
· Select Transmitter Control Mix 1.
· Select Launch phase using the flight phase switch.
· Set the mode to "Overwrite", select "Spoiler" as input and
"Throttle" as output.
· Leave the curve points at -100, 0, +100%; the switch
stays at "---".
· Use the flight phase switch to select Normal phase, and
repeat the settings for this flight phase.
· Now switch to the Landing flight phase; the Mode here
must be set to "Off".
Caution!:
Before you fly the model using this mixing arrangement,
it is absolutely essential to remove the propeller and
check all the settings extremely carefully. Pay particular
attention to the spoiler and throttle functions, the flight
phases and the mixers.
· Create an additional servo mixer (see image) for the right
motor, and enter the number of the second servo channel
under "output".
· Adjust the three-point-curve. (It should run symmetrically to
the curve of the first mixer).
