Governor

RPM to maintain the head speed desired. You can program values
for each switch position or flight mode. RPM values can be pro-
grammed in 0.5% steps.
To Program the Governor Function
1. Access the Governor menu option.
2. Program the RPM values by rotating the scroll wheel
to the desired value.

throttle, Cyclic-to-Throttle mixing prevents the throttle from
overdriving the servo.
IMPORTANT: Do not use Cyclic to throttle mix when using
a governor.

The Gyro menu option enables you to assign a gyro gain value to an independent switch
or a Flight Mode. Assign the receiver channel connected to the gyro, then assign the switch
for gyro options. You can also assign values to available switch positions (from 1 to 5 rates
are available, depending on the switch assigned). Make sure the gyro operates correctly
and compensates in the correct direction.

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.

the correct direction, move the flight mode switch to one of the

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.
