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
Motor disconnected from receiver
Open fuselage and make sure motor is
properly connected to the receiver
Extra propeller noise or
extra vibration
Damaged propeller, prop shaft, spinner or
motor
Replace damaged parts
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 power drawn
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 pro-
cess. Hold transmitter bind button or switch
until receiver is bound
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
LED on receiver fl ashes
rapidly and aircraft will
not respond to transmit-
ter (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 different model memory
(ModelMatch
™
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
Transmitter may have been bound to a
different model (or with a different DSM
Protocol)
Select the right transmitter or bind to the
new one
Aircraft or transmitter is too close to large
metal object, wireless source or another
transmitter
Move aircraft and transmitter to another
location and attempt linking again
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, con-
nect 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
Adjust controls on transmitter appropriately
