Troubleshooting Guide
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 ight
performance
Trim is not at neutral If you adjust trim more than 8 clicks, adjust the clevis to remove trim
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 y. Correct the direction settings (refer to the receiver manual), then y
Troubleshooting Guide AS3X
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 ight
time or aircraft
underpowered
Flight battery charge is low Completely recharge ight battery
Propeller installed backwards Install propeller with numbers facing forward
Flight battery damaged Replace ight battery and follow ight 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 enter
bind mode or initialize
Aircraft receiver is not level.
Raise tail wheel to make the fuselage close to level and hold steady until aircraft
enters bind mode or initializes.
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
ight 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 bind
process
Power off transmitter and repeat bind process. Hold transmitter bind
button or switch until receiver is bound
Motor turning the
wrong direction
Wires may be incorrectly connected to ESC.
Change any two of the wires to the motor. Or use Forward programming to change
direction of motor.
