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.
