MULTI-POINT MIXER – Example: ELIMINATE PITCH-COUPLING (Rudd - Elev Mixing)
The example below demonstrates a Multi-Point Program Mix for aircraft that pitch towards the
landing gear when holding rudder for knife-edge flight – commonly known as Pitch-Coupling.
If a mix is set up to provide an appropriate amount of up elevator for different amounts of rudder
input, the aircraft will fly straight without pitching to the gear while holding rudder during knife-
edge flight.
This Multi-Point mixer uses the Rudder as the Master and the Elevator as the Slave. The mix is
turned on and off with the GEAR switch.
The Mix parameters will be selected and set in the following order: Program Mix number,
Master, Slave, Switch, Set Points Travel/Direction, and Offset. This is generally a good
sequence to follow when setting up Multi-Point Programmable Mixers.

Slave (THROÆTHRO). The first THRO is the Master and the 2
nd
THRO represents the
Slave.
Highlight and select the first THRO to the left of the arrow to obtain a list of channels
and select RUDD as the Master.
3. Select Slave. Highlight and select THRO to the right of the arrow to obtain a list of
channels that can be used as the Slave. Highlight and select ELEV as the Slave.
4. Select Switch. Scroll down, highlight, and select GER as the switch to be used to turn the
mixer on and off. The GER indicator should now be in the upper or ON position at the
bottom of the display. Any of the switches along the bottom of the display can be used
and multiple switches can be used if so desired. The example is using only the Gear
switch.
