Problem

Possible Cause

Solution

Aircraft will not re-
spond 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

Spinner is not tight or fully seated in place

Tighten the spinner or remove the spinner and turn it 180 degrees.

Reduced fl ight time 
or aircraft under-
powered

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 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 
fl ight battery to aircraft

Aircraft or transmitter is too close to large metal ob-
ject, 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

Problem

Possible Cause

Solution

Oscillation

Flying over recommended 
airspeed

Reduce air speed

Damaged propeller or spinner

Replace propeller or spinner

Imbalanced propeller 

Balance the propeller. For more information, view John Redman’s propeller balancing video at www.
horizonhobby.com

Flight condition variations

Adjust gain to current fl ight conditions (wind, updrafts, local conditions (elevation, humidity, temperature, 
etc.))

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

Adjust gain to compensate for parts wear or replace worn parts (especially propeller, pivot points or servo)

Irregular servo rotation

Replace servo

Incorrect transmitter type (com-
puterized or non-computerized) 
assigned in receiver

Assign correct transmitter type in the receiver (refer to receiver manual)

If oscillation persists ....  

Decrease gain (refer to receiver manual)

Trim change 
when fl ight 
mode is switched

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 arm or the clevis

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.
