a) See the Warning label on the firewall. Do NOT exceed the maximum propeller size noted.

 

b) With power disconnected, double check the propeller to make sure it is not damaged or nicked in any way and that it is securely and safely mounted. Check before and after each flight.

 

c) Ensure the propeller turns true (no wobble) and that it is balanced and that all propeller fasteners are tight.

USING THE WRONG PROPELLER &/or OPERATING WITH EXCESSIVE VIBRATION WILL DESTROY THE MOTOR.

 

d) Ensure that your propeller is rotating clockwise when viewed from behind (looking forward as if you were in the cockpit) and that the prop is blowing air from the front of the model to the back.

 

f) If the propeller is rotating clockwise when viewed from behind but air is flowing from the back to the front of the model, the propeller is mounted on the motor backwards. Check and reinstall the propeller correctly. In general the brand logo and other writing on propellers should face forwards.

 

g) If the propeller is rotating backwards, reverse the black and white wire connections between the motor and the electronic speed control.
