FINAL SERVO ADJUSTMENT AND RADIO SETUP
Nowthattheradiosystemiscompletelyinstalledintothehelicopter,it’snecessarytocheckandadjustthe
following:
1. Servo Direction (Servo Reversing)
Check to ensure that all servos have been set to the correct direction.
2. Sub-Trim Settings
It’s suggested that the correct neutral settings be achieved without the use of the Sub-Trim function, as this
willaecttheneutralpositionoftheservos.Adjustthecyclictrimusingthecontrolrodsuntilaneutralhoveris
achieved.
3. Pitch/Throttle Curve Adjustment
Itisveryimportantthatthethrottleandpitchcurvesareadjustedproperlytoachievethebestperformance
fromyourhelicopter.Whenproperlyadjusted,themainrotorheadrpmshouldremainconsistentthroughoutall
maneuversandthrottlestickpositions.Aconstantrpmwillalsohelptoimprovetheeectivenessandaccuracyof
the tail rotor and gyro systems.

example, if you are a 3D pilot, then your maximum negative pitch will be -12, and your maximum positive pitch will
be +12.
Themaximumpitchrangethatyouwillrequirewillbe24°total.Themaximumpitchrange
mentioned above must be established through the use of the pitch travel value in the CCPM function.
Asmentionedpreviously,donottrytoestablishthemaximumpitchcurvevaluesthroughadjustment

values established earlier.
Please refer to the CCPM activation section for information on how to access the CCPM function. Once the CCPM
function has been activated, set the maximum positive pitch settings as mentioned above. Since the CCPM function
does not allow for independent travel settings for positive and negative pitch, it will be necessary to establish the
maximum positive pitch, since this is generally the largest degree of pitch in the pitch range. Once the maximum
positive pitch range is set, the maximum pitch range positive and negative can be reduced as needed through
the pitch curve function. Set the main rotor pitch gauge to the desired maximum pitch setting, then increase or
decrease the CCPM pitch travel (labeled Pitch or Ch 6) as needed until this pitch setting is achieved.
Once this procedure has been completed, the positive and negative pitch settings for each ight mode
canbeadjustedthroughtheradio’spitchcurvefunction.Pleaserefertoyourradio’sinstructionmanual
