AS3X
Problem
Control surfaces not at
neutral position when
transmitter controls are
at neutral
Model fl ies
inconsistently from
fl ight to fl ight
Controls oscillate in
fl ight, (model rapidly
jumps or moves)
Problem
Aircraft will not respond
to throttle but responds
to other controls
Extra propeller noise or
extra vibration
Reduced fl ight time or
aircraft underpowered
LED on receiver fl ashes
and aircraft will not bind
to transmitter (during
binding)
16
Possible Cause
Control surfaces may not have been
mechanically centered from factory
Aircraft was moved after the fl ight battery
was connected and before sensors
initialized
Aircraft was not kept immobile for 5
seconds after battery was plugged in
Trims are moved too far from neutral
position
Propellers are unbalanced, causing
excessive vibration
Possible Cause
Throttle stick and/or throttle trim too high
Throttle channel is reversed
Motor disconnected from receiver
Damaged propeller, gear or motor
Prop is out of balance
Flight battery charge is low
Propeller is 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
Transmitter too near aircraft during binding
process
Bind switch or button not held long enough
during bind process
Aircraft or transmitter is too close to large
metal object, wireless source or another
transmitter
Solution
Center control surfaces mechanically by
adjusting the U-bends on control linkages
Disconnect and reconnect the fl ight battery
while keeping the aircraft still for 5 seconds
Keep the aircraft immobile for 5 seconds after
plugging in the battery
Neutralize trims and mechanically adjust
linkages to center control surfaces
Remove propellers 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
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
