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.

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.
