Problem Possible Cause Solution
Aircraft will not respond
to throttle but responds to
other controls Throttle stick and/or throttle trim is too high Reset controls with throttle stick and throttle trim at
lowest setting
Throttle channel is reversed Reverse throttle channel on transmitter
Motor is unplugged from receiver Open fuselage and ensure the plug for the motor is
properly installed
Extra propeller noise or
extra vibration Damaged propeller, prop shaft or motor Replace damaged parts
Screw on prop shaft is too loose Tighten the prop shaft screw 1/2 turn
Reduced fl ight time or
aircraft underpowered Flight battery charge is low Completely recharge fl ight battery
Propeller is installed backwards Install propeller with numbers facing forward
Flight battery is 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 is too low for fl ight conditions Replace battery or use a larger capacity battery
LED on receiver fl ashes
rapidly and aircraft will not
bind to transmitter (during
binding) Transmitter is 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 was not held while
transmitter was powered on Power off transmitter and repeat bind process
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 is bound to a 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 (See Transmitter and Model
Setup page).
Only one elevon responds
to controls Transmitter’s elevon function not activated Activate elevon function on transmitter. In some
transmitters, this function is also known as
Delta Wing.
Motor loses power Damage to motor or power components Do a check of motor and power components for
damage (replace as needed)
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 and/or set sub trims
to Zero and adjust linkages mechanically.
