spinner
Replace propeller or spinner
Imbalanced propeller
Balance the propeller. For more information, view John Redman’s propeller balancing video at www.

Motor vibration Replace parts or correctly align all parts and tighten fasteners as needed
Loose receiver Total system failure. 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
Trim is at extreme
and aircraft does not
fl y straight or level
Trim is not at neutral If you adjust trim more than 4 clicks, adjust the clevis to mechanically remove trim
Problem Possible Cause Solution
Aircraft will not re-
spond to throttle but
responds to other
controls
Throttle not at lowest position 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
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
