The Self-Tightening Propellers are a set of two 9" propellers compatible with the Quadcopter. Both propellers are rotating props while one is clockwise (CW) and the other is counter-clockwise (CCW). These Self-Tighening Propellers are specially designed to be used. They have built-in threads to allow self tightening while in flight and require a special spanner to tighten before flight. The self-tightening design avoids prop becoming loose during flight.
These props will only work with the right and left handed threaded motors.
Easy to fix as have self locking property.
