AS3X
Problem
Control surfaces not at Control surfaces may not have been
neutral position when mechanically centered from factory
transmitter controls are
at neutral
ESC/receiver does Aircraft was not kept immobile for 5
seconds
not arm when the
battery is connected
Aircraft oscillates in Incorrect fl ight mode
fast forward fl ight
Controls oscillate in Propeller is unbalanced, causing excessive
fl ight, (model rapidly vibration
jumps or moves)
Problem
Aircraft will not respond Throttle stick and/or throttle trim too high
to throttle but responds
to other controls
Throttle channel is reversed
Motor disconnected from receiver
Extra propeller noise or Damaged propeller, spinner or motor
extra vibration
Prop screw is too loose
Prop is out of balance
Reduced fl ight time or Flight battery charge is low
aircraft underpowered
Propeller installed backwards
Flight battery damaged
Flight conditions may be too cold
Battery capacity too low for fl ight conditions Replace battery or use a larger capacity
LED on receiver fl ashes Transmitter too near aircraft during binding
and aircraft will not bind process
to transmitter (during
binding)
Bind switch or button not held long enough
during bind process
Aircraft or transmitter is too close to large

Possible Cause
Possible Cause
Solution

adjusting the U-bends on control linkages
Disconnect and reconnect the fl ight
battery while keeping the aircraft still for
5 seconds with throttle sitck in lowest
position.
Decrease throttle, then change to
General Flight or a Standard AS3X fl ight
mode
Remove propeller and rebalance or replace it
if damaged
Solution
Reset controls with throttle stick and throttle
trim at lowest setting
Reverse throttle channel on transmitter
Open fuselage and make sure motor is
connected to the receiver
Replace damaged parts
Tighten the prop screw
Remove and balance propeller, or replace
with a balanced propeller.
Completely recharge fl ight battery
Install propeller with numbers facing forward
Replace fl ight battery and follow fl ight battery
instructions
Make sure battery is warm before use
battery
Power off transmitter, move transmitter a
larger distance from aircraft, disconnect and
reconnect fl ight battery to aircraft and follow
binding instructions
Power off transmitter and repeat bind
process. Hold transmitter bind button or
switch until receiver is bound
Move aircraft and transmitter to another
location and attempt binding again
