Problem Possible Cause Solution
Aircraft will not respond
to throttle but responds to
other controls
Throttle not at idle and/or throttle trim 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
Motor disconnected from ESC Make sure motor is connected to the ESC
Extra noise or extra vibra-
tion during throttle opera-
tion
Damaged rotor, collet or motor Replace damaged parts
Rotor is out of balance Balance or replace rotor
Rotor nut is too loose Tighten the rotor nut
Reduced ight time or air-
craft underpowered
Flight battery charge is low Completely recharge ight battery
Flight battery damaged
Replace ight battery and follow ight battery
instructions
Flight conditions may be too cold Make sure battery is warm before use
Battery capacity too low for flight conditions Replace battery or use a larger capacity battery
Aircraft will not connect
(during binding) to
transmitter
Transmitter too near aircraft during binding process
Move powered transmitter a few feet from aircraft,
disconnect and reconnect ight battery to aircraft
Aircraft or transmitter is too close to large metal object,
wireless source or another transmitter
Move aircraft and transmitter to another location
and attempt binding again
Flight battery/transmitter battery charge is too low Replace/recharge batteries
Bind switch or button not held long enough during bind
process
Power off transmitter and repeat bind process. Hold
transmitter bind button or switch until receiver is bound
Aircraft will not connect
(after binding) to
transmitter
Transmitter too near aircraft during connecting process
Move powered transmitter a few feet from aircraft,
disconnect and reconnect ight battery to aircraft
Aircraft or transmitter is too close to large metal object,
wireless source or another transmitter
Move aircraft and transmitter to another location and
attempt connecting again
Aircraft bound to different model memory
(ModelMatch
TM
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 aircraft
using different DSM protocol
Bind aircraft to transmitter
Control surface does not
move
Control surface, control horn, linkage or servo damage Replace or repair damaged parts and adjust controls
Wire damaged or connections loose
Do a check of wires and connections, connect or replace
as needed
Transmitter is not bound correctly or the incorrect
airplanes was selected
Re-bind or select correct airplanes in transmitter
Flight battery charge is low Fully recharge ight battery
BEC (Battery Elimination Circuit) of the ESC is damaged Replace ESC
Controls reversed Transmitter settings are reversed
Perform the Control Direction Test and adjust the
controls on the transmitter appropriately
Motor power pulses then
motor loses power
ESC uses default soft Low Voltage Cutoff (LVC)
Recharge 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 battery
