Problem
Possible Cause
Solution
Aircraft will not re-
spond 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 propeller noise
or extra vibration
Damaged propeller and spinner, collet or motor
Replace damaged parts
Propeller is out of balance
Balance or replace propeller
Prop nut is too loose
Tighten the prop nut
Spinner is not tight or fully seated in place
Tighten the spinner or remove the spinner and turn it 180 degrees.
Reduced fl ight time
or aircraft under-
powered
Flight battery charge is low
Completely recharge fl ight battery
Propeller installed backwards
Install propeller with numbers facing forward
Flight battery 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 C rating is too low
Replace battery or use battery with correct C rating
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 fl 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
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 con-
nect (after binding)
to transmitter
Transmitter too near aircraft during connecting 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,
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 (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 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 model
was selected
Re-bind or select correct model in transmitter
Flight battery charge is low
Fully recharge fl 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
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 battery
