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
