Trouble Shooting Guide

Problem
Throttle not at lowest position or throttle trim too high
Aircraft will not respond
Throttle servo travel is lower than 100%
to throttle but responds to
other controls
Throttle channel is reversed
Motor disconnected from ESC
Damaged propeller and spinner, collet or motor
Propeller is out of balance
Extra propeller noise or extra
Prop nut is too loose
vibration
Spinner is not tight or fully seated in place
Flight battery charge is low
Propeller installed backwards
Reduced flight time or
Flight battery damaged
aircraft underpowered
Flight conditions may be too cold
Battery capacity too low for flight conditions
Transmitter too near aircraft during binding process
Aircraft or transmitter is too close to large metal object, wireless source or
another transmitter
Aircraft will not Bind (during
The bind plug is not installed correctly in the bind port
binding) to transmitter
Flight battery/transmitter battery charge is too low
Bind switch or button not held long enough during bind process
Transmitter too near aircraft during connecting
process
Aircraft or transmitter is too close to large metal
object, wireless source or another transmitter
Aircraft will not connect
Bind plug left installed in bind port
(after binding) to transmitter
Aircraft bound to different model memory
(ModelMatch
Flight battery/Transmitter battery charge is too low
Transmitter may have been bound using different DSM protocol
Control surface, control horn, linkage or servo
damage
Wire damaged or connections loose
Control surface does not
move
Transmitter is not bound correctly or the incorrect model was selected
Flight battery charge is low
BEC (Battery Elimination Circuit) of the ESC is
damaged
Controls reversed Transmitter settings are reversed
ESC uses default soft Low Voltage Cutoff (LVC)
Motor power pulses then
Weather conditions might be too cold
motor loses power
Battery is old, worn out, or damaged
Battery C rating might be too small
Aircraft control surfaces do
not move after switch is Aircraft was moving during initialization
turned on
Possible Cause
radios only)

Solution
Reset controls with throttle stick and throttle trim at
lowest setting
Make sure throttle servo travel is 100% or greater
Reverse throttle channel on transmitter
Make sure motor is connected to the ESC
Replace damaged parts
Balance or replace propeller
Tighten the prop nut
Tighten the spinner or remove the spinner and turn
it 180 degrees
Completely recharge flight battery
Install propeller with numbers facing forward
Replace flight battery and follow flight battery
instructions
Make sure battery is warm before use
Replace battery or use a larger capacity battery
Move powered transmitter a few feet from aircraft,
disconnect and reconnect flight battery to aircraft
Move aircraft and transmitter to another location and
attempt binding again
Install bind plug in bind port and bind the aircraft to
the transmitter
Replace/recharge batteries
Power off transmitter and repeat bind process. Hold
transmitter bind
button or switch until receiver is bound
Move powered transmitter a few feet from aircraft,
disconnect and reconnect
flight battery to aircraft
Move aircraft and transmitter to another location and
attempt connecting again
Rebind transmitter to the aircraft and remove the
bind plug before cycling power
Select correct model memory on transmitter
Replace/recharge batteries
Bind aircraft to transmitter
Replace or repair damaged parts and adjust controls
Do a check of wires and connections, connect or
replace as needed
Re-bind or select correct model in transmitter
Fully recharge flight battery
Replace ESC
Perform the Control Direction Test and adjust the
controls on transmitter
appropriately
Recharge flight battery or replace battery that is no
longer performing
Postpone flight until weather is warmer
Replace battery
Use recommended battery
Keep aircraft still during initialization
