Mixing
Cyclic to Throttle
Cyclic-to-throttle mix prevents rpm loss when aileron, elevator or
rudder inputs are given. This mix advances the throttle position
with cyclic or rudder control to maintain rpm. At full throttle,
Cyclic-to-Throttle mixing prevents the throttle from over driving
the servo.
IMPORTANT: Do not use Cyclic to throttle mix when using a
governor.
To verify that the Cyclic to Throttle mix is working properly and in
the correct direction, move the flight mode switch to one of the
active positions. Move the programmed cyclic or rudder channel,
noting the throttle position. The throttle position should increase.
If the throttle decreases, then the opposite value (positive vs.
negative) is needed.
Swashplate
The Swashplate Mix typically corrects swashplate timing issues by
mixing Aileron to Elevator and Elevator to Aileron. When adjusted
correctly, the Swashplate causes the helicopter to roll and pitch
accurately with minimal interaction.
Tail Curve
The Tail Curve function mixes tail rotor input with the throttle/
collective function to counter torque from the main rotor blades
when using a non-heading hold (tail lock) gyro or when using
rate mode on a gyro. See Pitch Curve for more information on
programming curves.
