Troubleshooting Guide AS3X
Problem
Possible Cause
Solution
Oscillation
Damaged propeller or spinner
Replace propeller or spinner
Imbalanced propeller
Balance the propeller
Motor vibration
Replace parts or correctly align all parts and tighten fasteners as needed
Loose receiver
Align and secure receiver in fuselage
Loose aircraft controls
Tighten or otherwise secure parts (servo, arm, linkage, horn and control surface)
Worn parts
Replace worn parts (especially propeller, spinner or servo)
Irregular servo movement
Replace servo
Inconsistent flight
performance
Trim is not at neutral
If you adjust trim more than 8 clicks, Adjust by loosening screw in pushrod keeper on
servo and move pushrod then re-tighten screw.
Sub-Trim is not at neutral
No Sub-Trim is allowed. Adjust the servo linkage
Aircraft was not kept immobile for 5
seconds after battery connection
With the throttle stick in lowest position. Disconnect battery, then reconnect battery and
keep the aircraft still for 5 seconds
Incorrect response to the AS3X
Control Direction Test
Incorrect direction settings in the receiver,
which can cause a crash
DO NOT fly. Correct the direction settings (refer to the receiver manual), then fly
Problem
Possible Cause
Solution
Aircraft will not
respond to throttle
but responds to other
controls
Throttle not at idle and/or throttle trim too high
Reset controls with throttle stick and throttle trim at lowest setting
Throttle servo travel is lower than 100%
Make sure throttle servo travel is 100% or greater
Throttle channel is reversed
Reverse throttle channel on transmitter
Motor disconnected from ESC
Make sure motor is connected to the ESC
Extra propeller noise
or extra vibration
Damaged propeller and spinner, collet or motor
Replace damaged parts
Propeller is out of balance
Balance or replace propeller
Prop nut is too loose
Tighten the prop nut
Reduced flight
time or aircraft
underpowered
Flight battery charge is low
Completely recharge flight battery
Propeller installed backwards
Install propeller with numbers facing forward
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
Aircraft will not Bind
(during binding) to
transmitter
Transmitter too near aircraft during binding process
Move powered transmitter a few feet from aircraft, disconnect and reconnect
flight battery to aircraft
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
The bind plug is not installed correctly in the bind port Install bind plug in bind port and bind the aircraft to the transmitter
Flight battery/transmitter battery charge is too low
Replace/recharge batteries
Bind switch or button not held long enough during the
bind process
Power off transmitter and repeat bind process. Hold transmitter bind button or switch
until receiver is bound
Aircraft will not
connect (after
binding) to
transmitter
Transmitter too near aircraft during connecting process Move powered transmitter a few feet from aircraft, disconnect and reconnect flight
battery to aircraft
Aircraft or transmitter is too close to large metal object,
wireless source or another transmitter
Move aircraft and transmitter to another location and attempt connecting again
Bind plug left installed in bind port
Rebind transmitter to the aircraft and remove the bind plug before cycling power
Aircraft bound to different model memory
(ModelMatchTM radios only)
Select correct model memory on transmitter
Flight battery/Transmitter battery charge is too low
Replace/recharge batteries
Transmitter may have been bound to a different
aircraft using different DSM protocol
Bind aircraft to transmitter
