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
