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.
