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
Excessive fan
noise or excessive
vibration
Damaged fan, nose cone, collet or motor
Replace damaged parts
Fan is out of balance
Balance or replace fan
Fan screw is loose
Tighten the fan screw
Reduced flight
time or aircraft
underpowered
Flight battery charge is low
Completely recharge flight battery
Flight battery damaged
Replace flight battery and follow flight battery instructions
Flight conditions may be too cold
Make sure battery is not cold before use (Do not apply heat to the battery)
Battery capacity too low for flight conditions
Replace battery or use a larger capacity battery
Aircraft will not bind
(during binding) to
transmitter
Transmitter too near aircraft during binding process
Move powered transmitter a few feet from aircraft, disconnect and reconnect flight
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
The bind plug is not installed correctly in the bind port Install bind plug in bind port and bind the aircraft to the transmitter
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 flight
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
Bind plug left installed in bind port
Rebind transmitter to the aircraft and remove the bind plug before cycling power
Aircraft bound to different model memory
(ModelMatchTM 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 flight 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 transmitter appropriately
Motor power pulses
then motor loses
power
ESC uses default soft Low Voltage Cutoff (LVC)
Recharge flight 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 low
Use recommended battery
