Troubleshooting Guide

Problem Possible Cause Solution

Aircraft will not respond

to throttle but responds to

other controls

Throttle is not set to lowest stick postiion and/or throttle trim

is too high

Reset controls with throttle stick and throttle trim

at lowest setting

Throttle servo travel is lower than 100% Make sure throttle servo travel is 100% or greater

Throttle channel is reversed Reverse throttle channel on transmitter

Extra fan noise or extra

vibration

Damaged rotor and spinner, collet or motor Replace damaged parts

Rotor is out of balance Balance or replace rotor

Reduced ﬂ ight time or air-

craft underpowered

Flight battery charge is low Completely recharge ﬂ ight battery

Flight battery is damaged Replace ﬂ ight battery and follow ﬂ ight battery instructions

Flight conditions may be too cold Make sure battery is warm before use

Battery capacity may be too low for ﬂ ight conditions Replace battery or use a larger capacity battery

Aircraft will not Bind (dur-

ing binding) to transmitter

Transmitter is too near aircraft during binding process Move powered transmitter a few feet from aircraft,

disconnect and reconnect ﬂ ight battery to aircraft

Aircraft or transmitter is too close to large metal object Move aircraft or transmitter away from large metal object

Bind plug is not installed correctly Install bind plug and bind aircraft to transmitter

Flight battery/Transmitter battery charge is too low Replace/recharge batteries

ESC switch is off Power on ESC switch

Aircraft will not link (after

binding) to transmitter

Transmitter is too near aircraft during linking process Move powered transmitter a few feet from aircraft,

disconnect and reconnect ﬂ ight battery to aircraft

Aircraft or transmitter is too close to large metal object Move aircraft or transmitter away from large metal object

Bind plug is left installed Rebind transmitter to aircraft and remove bind plug before

cycling power

Aircraft bound to different model memory

(ModelMatch™ radios only)

Select correct model memory on transmitter

Flight battery/Transmitter battery charge is too low Replace/recharge batteries

Transmitter may have been bound to a different model

(using different DSM Protocol)

Bind aircraft to transmitter

ESC switch is off Power on ESC switch

Control surface does not

move

Control surface, control horn, linkage or servo damage Replace or repair damaged parts and adjust controls

Wire is damaged or connections are loose Do a check of wires and connections, connect

or replace as needed

Transmitter is not bound correctly or the incorrect model

was selected

Re-bind or select correct model in transmitter

BEC (Battery Elimination Circuit) of the ESC is damaged Replace ESC

ESC switch is off Power on ESC switch

Controls reversed Transmitter settings are reversed Do the Control Direction Test and adjust controls on

transmitter appropriately

Motor power pulses then

motor loses power

ESC uses default soft Low Voltage Cutoff (LVC) Recharge ﬂ ight battery or replace battery that is no

longer performing

Weather conditions might be too cold Postpone flight until weather is warmer

Battery is old, worn out or damaged Replace battery

Battery C rating might be too small Use recommended 30C battery
