Problem
Possible Cause
Solution
Control surfaces not at neutral
position when transmitter
controls are at neutral
Control surfaces not mechanically centered
from factory
Center control surfaces mechanically by
adjusting the U-bends on control linkages
Aircraft was moved after the fl ight battery
was connected and before sensors initialized
Disconnect and reconnect the fl ight battery
while keeping the aircraft still for 5 seconds
Model fl ies inconsistently
from fl ight to fl ight
Trims are moved too far from neutral position
Neutralize trims and mechanically adjust
linkages to center control surfaces
Controls oscillate in fl ight
(model rapidly jumps or moves)
Rotor is unbalanced,
causing excessive vibration
Remove rotor and motor. Check motor shaft for
straightness and replace rotor if damaged

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
Motor disconnected from receiver
Open fuselage and make sure motor is
connected to the receiver
Extra motor noise or extra
vibration
Damaged rotor or motor
Replace damaged parts
Rotor out of balance
Balance or replace the rotor
Reduced fl ight time or
aircraft underpowered
Flight battery charge is low
Completely recharge fl ight battery
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 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
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
Adjust controls on transmitter appropriately
