Possible Cause
Replace propeller or spinner
Balance the propeller
Replace parts or correctly align all parts and tighten fasteners as needed
Align and secure receiver in fuselage
Tighten or otherwise secure parts (servo, arm, linkage, horn and control surface)
Replace worn parts (especially propeller, spinner or servo)
Replace servo
If you adjust trim more than 8 clicks, adjust the clevis to remove trim
No Sub-Trim is allowed. Adjust the servo linkage
With the throttle stick in lowest position. Disconnect battery, then reconnect battery and keep the
aircraft still for 5 seconds
DO NOT fl y. Correct the direction settings (refer to the receiver manual), then fl y

Solution
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 fl ight battery
Install propeller with numbers facing forward
Replace fl ight battery and follow fl ight 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
fl ight battery to aircraft
Move aircraft and transmitter to another location and attempt binding again
Install bind plug in bind port and bind the aircraft to the transmitter
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
fl ight 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 airplanes in transmitter
Fully recharge fl ight battery
Replace ESC
Perform the Control Direction Test and adjust the controls on transmitter appropriately
Recharge fl ight battery or replace battery that is no longer performing
Postpone flight until weather is warmer
Replace battery
Use recommended battery
