Gyro

The Gyro function supports setting gain for gyros that operate
on transmitter programming or with flight modes. 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.

Governor

The Governor function adjusts the engine RPM. You can program
values for each switch position or flight mode. RPM values
can be programmed in 0.5% Steps. You can also program the
channel that is driven by the gyro.
Programming the Governor Function
Press the Roller from the Main or Telemetry display to access the
Function List.
Selecting a Switch
The Governor default setting is inhibited. For activation, highlight
and press the Roller on the deactivated box. Select a switch for
that function.

Tail Curve

This 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 common section for more info on curves)

HELI Mixing

Cyclic to Throttle
Cyclic-to-throttle mix prevents rpm decay when aileron, elevator
and or rudder inputs are given. This mix advances the throttle
position with cyclic or rudder control to maintain rpm. At full
throttle, programming prevents the throttle from overdriving the
servo.
IMPORTANT: Do not use Cyclic to throttle mix when using a
governor.
To verify that Cyclic mix is working properly and in the correct
direction, place the flight mode switch in one of the active
positions. Move the programmed cyclic or rudder channel noting
the throttle position. The throttle position should increase.
If it decreases then the opposite value (positive vs. negative) is
needed.

Assigning an Output Channel
In this menu, you can assign the Governor output channel. The
Governor and Gyro must be on different channels. Rotate the
Roller to the channel box, press the Roller and select the channel
that you want to use for the Governor. Usually this is Aux 2.
Programming the RPM values
Rotate the Roller to the desired value, press the Roller and rotate
it to the value you want to set.
Please note: The value in the display is the corrected value.
0% is 1.500ms or OFF for most governors. Repeat this for all
governor settings.
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 inter-reaction.
