Swashplate

The Swashplate menu option enables you to adjust the following:

• Swashplate Mix
• Exponential
• E-Ring
• Elevator Compensation

Use positive or negative Swashplate mix values as needed for

correct direction response of the helicopter.

Before making adjustments to the Swashplate mix, make sure the

throttle/collective pitch input moves the entire swashplate up or

down. If the servos are not moving in the same direction, reverse

them as necessary in the Servo Setup menu option.
When the entire swashplate moves up or down:

1. Adjust the mix value for the Aileron and Elevator channels. If

the servos do not move in the correct direction, change the

direction of the mix—for example, a positive value instead of

a negative value.

2. Adjust the mix value for the Pitch. If the swashplate does not

move in the correct direction, change the direction of the value

(negative instead of positive).

Always enable Expo when using a standard rotating-arm servo.

The Expo delivers linear movement of the swashplate from a

standard rotary servo. When Expo is inhibited, the arm on a

rotary servo moves on a curved path with decreased swashplate

movement at the extremes of the servo arm travel.
NOTICE: Do not enable Expo when using a linear servo.
Electronic E-Ring

This feature prevents over driving servos by limiting servo travel if

the sum of your cyclic and pitch inputs exceeds servo limits.

Gyro

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 4 rates are available, depending on the switch
assigned). Make sure the gyro operates correctly and
compensates in the correct direction.

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.
