Possible Cause
Damaged propeller or spinner Replace propeller or spinner
Balance the propeller. For more information, view John Redman's propeller balancing video at
Imbalanced 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
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

Solution
Reset controls with throttle stick and throttle trim at lowest setting
Make sure throttle servo travel is 100% or greater
Reverse throttle channel on transmitter
Make sure motor is connected to the ESC
Replace damaged parts
Balance or replace propeller
Tighten the prop nut
Completely recharge flight battery
Install propeller with numbers facing forward
Replace flight battery and follow flight battery instructions
Make sure battery is warm before use
Replace battery or use a larger capacity battery
Move powered transmitter a few feet from aircraft, disconnect and reconnect
flight battery to aircraft
Move aircraft and transmitter to another location and attempt binding again
Replace/recharge batteries
Power off transmitter and repeat bind process. Hold transmitter bind button or
switch until receiver is bound
Move powered transmitter a few feet from aircraft, disconnect and reconnect
flight battery to aircraft
Move aircraft and transmitter to another location and attempt connecting again
Rebind transmitter to the aircraft and remove the bind plug before cycling power
Select correct model memory on transmitter
Replace/recharge batteries
Bind aircraft to transmitter
Replace or repair damaged parts and adjust controls
Do a check of wires and connections, connect or replace as needed
Re-bind or select correct airplane in transmitter
Fully recharge flight battery
