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
Flight battery charge is low
Fully recharge flight battery
Extra motor noise or
extra vibration
Damaged rotor or motor
Replace damaged parts
Rotor out of balance
Balance or replace the rotor
Reduced flight time or
aircraft underpowered
Flight battery charge is low
Completely recharge flight battery
Flight battery damaged
Replace flight battery and follow flight battery
instructions
Flight conditions may be too cold
Make sure battery is warm before use
Battery capacity too low for flight conditions Replace battery or use a larger capacity
battery
LED on receiver flashes
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 flight 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
Troubleshooting Guide
AS3X
Problem
Possible Cause
Solution
Control surfaces not at
neutral position when
transmitter controls are
at neutral
Control surfaces may not have been
mechanically centered from factory
Center control surfaces mechanically by
adjusting the U-bends on control linkages
Aircraft was moved after the flight battery
was connected and before sensors
initialized
Disconnect and reconnect the flight battery
while keeping the aircraft still for 5 seconds
Model flies
inconsistently from
flight to flight
Aircraft was not kept immobile for 5
seconds after battery was plugged in
Keep the aircraft immobile for 5 seconds after
plugging in the battery
Trims are moved too far from neutral
position
Neutralize trims and mechanically adjust
linkages to center control surfaces
Controls oscillate in
flight, (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
Post Flight Checklist
1. Disconnect the flight battery from the ESC
(Required for safety and battery life).
2. Power OFF the transmitter.
3. Remove the flight battery from the aircraft.
4. Recharge the flight battery.
5. Store the flight battery apart from the aircraft
and monitor the battery charge.
6. Make note of the flight conditions and flight
plan results, planning for future flights.
