AS3X/SAFE
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 fl ight bat-
tery was connected and before sensors
initialized
Disconnect and reconnect the fl ight
battery while keeping the aircraft still for
5 seconds
Aircraft was not upright, level on its
gear when powered on.
Switch aircraft to AS3X mode and
repower on keeping aircraft upright, level
on its gear.
Model fl ies
inconsistently from
fl ight to fl ight
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
fl ight, (model rapidly
jumps or moves)
Propeller is unbalanced, causing exces-
sive vibration
Remove propeller and rebalance or
replace it if damaged
Prop screw is too loose, causing vibration Tighten the prop screw
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 propeller noise
or extra vibration
Damaged propeller, spinner or motor
Replace damaged parts
Prop screw is too loose
Tighten the prop screw
Prop is out of balance
Remove and balance propeller, or replace
with a balanced propeller
Reduced fl ight time or
aircraft underpowered
Flight battery charge is low
Completely recharge fl ight battery
Propeller installed backwards
Install propeller with numbers facing
forward
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 ash-
es 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
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
