The Rudder 4 Aileron mixing percentage value is a ratio of aileron travel to rudder travel. For example, when the
Rudder-Left 4 Left Aileron and the Rudder-Right 4 Left Aileron mixing percentage values are set to 10%, the left aileron will
travel 1/10th the amount that the rudder travels in both directions. This mix is Linear.
Because you can program the Rudder 4 Aileron percentage value separately for both directions of rudder travel, it's
possible to program the mix to either make the ailerons move up or down with right and left rudder control, make the ailerons
move up and down with right and left rudder control, or make the ailerons move up or down with right or left rudder control.
Gear to Elevator Mixing
The Gear to Elevator Mixing function allows you to mix a percentage of elevator control with landing gear control. When you raise
and lower the landing gear, the elevator will move up and down. The Gear to Elevator Mixing function is typically used on scale
sailplanes that feature retractable landing gear. It is used to compensate for pitch changes when the landing gear is lowered.
The amount and the direction that the elevator moves when the landing gear is raised and lowered is adjusted by changing the
Gear 4 Elevator mixing percentage value either positive or negative.
IMPORTANT The Gear to Elevator Mixing function must be assigned to a Switch Position Number before it can be
Activated. The landing gear function must be assigned to a Switch Position Number, too. For more information, see page 45.
1) Press the Navigation Pad 56 to highlight MIXING, then press the
ENTER key to display the MIXING menu. The AI 4 RU1 sub-menu will
be highlighted by default.
2) Press the Navigation Pad 6 to highlight GE 4 EL, then press the
ENTER key to display the GE 4 EL menu. The cursor will default to
COMMON>COM.
3) Press the YES/+ or NO/- keys to choose the desired COM or SEP
option as described previously.
4) Press the Navigation Pad 6 to highlight GE 4 EL>0%.
5) Press the YES/+ or NO/- keys to change the Gear 4 Elevator mixing
percentage value.
The Gear 4 Elevator mixing percentage value is a ratio of elevator travel to landing gear travel. Because the landing gear is
assigned to a non-proportional switch, the Gear 4 Elevator mixing percentage value programmed will result in only half the
programmed movement. For example, when the Gear 4 Elevator mixing percentage value is set to 20%, the elevator will travel
1/10th the amount that the landing gear travels. Since the landing gear channel is not proportional, the elevator will jump
to the Gear 4 Elevator mixing percentage value programmed.
GE 4 EL setting range is -100% to 100%. The default setting is 0%. When the percentage value is increased from 0% to 100%,
elevator travel will increase in one direction in relation to landing gear travel. When the percentage value is decreased
from 0% to -100%, elevator travel will increase in the opposite direction in relation to landing gear travel.
Motor to Elevator Mixing
The Motor to Elevator Mixing function allows you to mix a percentage of elevator control with motor control. When the motor is
turned on and off, the elevator will move up and down. The Motor to Elevator Mixing function is typically used to compensate for
pitch changes when the motor is turned on and off. For example, when the motor is turned on, the aircraft might pitch up more
than desired. You can mix in down elevator to compensate for this. The amount and the direction that the elevator moves when
the motor is turned on and off is adjusted by changing the Motor 4 Elevator mixing percentage value either positive or negative.
IMPORTANT The Motor to Elevator Mixing function must be assigned to a Switch Position Number before it can be
Activated. The motor function must be assigned to a Switch Position Number, too. For more information, see page 45. The
motor function can also be assigned to a control stick or an Auxiliary Lever, too. For more information, see page 151.
