Troubleshooting Guide
Problem Possible Cause Solution
Aircraft will not respond
to throttle but responds to
other controls Throttle stick and/or throttle trim too high Reset controls with throttle stick and throttle trim at
lowest setting
Throttle channel is reversed Reverse throttle channel on transmitter
Extra propeller noise or
extra vibration Damaged propeller, spinner, prop shaft or motor Replace damaged parts
Nut on prop shaft is too loose Tighten the prop shaft nut 1/2 turn
Reduced fl ight time or
aircraft underpowered 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 capacity too low for fl ight conditions Replace battery or use a larger capacity battery
LED on receiver fl ashes
and aircraft will not bind
to transmitter (during
binding) Transmitter too near aircraft during binding
process Power off transmitter, move transmitter a larger
distance from aircraft, disconnect and reconnect fl ight
battery to aircraft and follow binding instructions
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
LED on receiver fl ashes
rapidly and aircraft will
not respond to transmitter
(after binding) Less than a 5-second wait between fi rst
powering on transmitter and connecting fl ight
battery to aircraft Leaving transmitter on, disconnect and reconnect
fl ight battery to aircraft
Aircraft bound to diff erent model memory
(ModelMatch
TM radios only)
Select correct model memory on transmitter and
disconnect and reconnect fl ight battery to aircraft
Flight battery/transmitter battery charge is
too low Replace/recharge batteries
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
Flight battery charge is low Fully recharge fl ight battery
Control linkage does not move freely Make sure control linkage moves freely
Controls reversed Transmitter settings reversed Do the Control Direction Test and adjust controls on
transmitter appropriately
Motor loses power Damage to motor, propeller shaft or power
components Do a check of moter, prop shaft and power
components for damage (replace as needed)
Nut on prop shaft is too tight Loosen prop shaft nut until propeller shaft turns freely
Motor power quickly
decreases and increases
then motor loses power Battery power is down to the point of receiver/
ESC Low Voltage Cutoff (LVC) Recharge fl ight battery or replace battery that is no
longer performing
Servo locks or freezes at
full travel Travel adjust value is set above 100%
overdriving the servo. Set Travel adjust to 100% or less
Plane turns left or right
in fl ight and aileron and
rudder control centering
has been checked Propellers are turning at signifi cantly diff erent
speeds (RPM). (Higher RPM will cause the
motor to make a higher pitch sound) Verify that propeller, prop shaft and motor are turning
freely and adjust if needed. If no issues are found,
replace motor that is turning signifi cantly lower RPM.
