CAUTION:
Always disconnect the fl ight battery before performing motor service.
Disassembly
1. Remove the two screws from the fan unit cover and pull the cover off of the
fuselage.
2. Remove the four screws from the fan unit tabs.
3. Pull the fan unit out of the fuselage, take note of the wiring order, and
disconnect the motor leads from the ESC.
4. Remove the nose cone screw, nose cone and rotor nut from the rotor adaptor.
5. Remove the rotor by pulling it off the rotor adaptor.
6. Remove the rotor adaptor from the motor shaft.
7. Remove the four 3mm hex head screws that hold the motor in the fan housing.
Assembly
Assemble in reverse order.
• Correctly align and connect the motor wire colors with the ESC wires.
• Install the rotor as shown.
• Tighten the nut on the motor adaptor to secure the rotor into place.

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
Excessive impeller
noise or Excessive
vibration
Damaged impeller, nose cone, collet or motor
Replace damaged parts
Impeller is out of balance
Balance or replace impeller
Impeller nut is too loose
Tighten the impeller nut
Reduced fl ight
time or aircraft
underpowered
Flight battery charge is low
Completely recharge fl ight battery
Flight battery damaged
Replace fl ight battery and follow fl ight battery instructions
Flight conditions may be too cold
Make sure battery is not cold before use (Do not apply heat to the battery)
Battery capacity too low for fl ight 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 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

Troubleshooting Guide AS3X
Problem
Possible Cause
Solution
Oscillation
Damaged rotor or nose cone
Replace rotor or nose cone
Imbalanced rotor
Balance the rotor
Motor vibration
Replace parts or correctly align fan unit or other 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 rotor, nose cone, or servo)
Irregular servo movement
Replace servo
Inconsistent fl ight
performance
Trim is not at neutral
If you adjust trim more than 8 clicks, adjust the ball link 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), then fl y
