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 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
Aircraft will not Bind
to transmitter
(during binding)
Transmitter too near aircraft during binding process
Move powered transmitter a few feet from aircraft, disconnect and reconnect fl 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
Aircraft will not connect to
transmitter (after binding)
Transmitter too near aircraft during connecting process
Move powered transmitter a few feet from aircraft, disconnect and reconnect fl 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 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
(ModelMatch
TM
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
Control surface
does not move
Control surface, control horn, linkage or servo damage Replace or repair damaged parts and adjust controls
Wire damaged, connections loose or reversed Do a check of wires and connections, connect or replace as needed
Transmitter is not bound correctly or the incorrect airplanes
was selected
Re-bind or select correct airplanes in transmitter
Flight battery charge is low Fully recharge fl ight battery
BEC (Battery Elimination Circuit) of the ESC is damaged Replace ESC
Controls reversed
Transmitter settings are reversed Set all transmitter control directions to normal
Elevons connected to the wrong receiver ports Connect the elevon servos to the correct receiver ports
Troubleshooting Guide
AS3X Troubleshooting Guide
Problem Possible Cause Solution
Oscillation in fl ight
Damaged propeller Replace propeller
Propeller out of balance 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 or servo)
Irregular servo movement Replace servo
Too high of gain value in AR636 Refer to the AR636 manual to reduce gain value.
Inconsistent fl 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 fl y. Correct the direction settings (refer to the receiver manual)
