The DJI 9450 Self-Tightening Propeller Set for Phantom 3 is a set of two 9" propellers for the DJI Phantom 3 Advanced or Professional quadcopter. It features one clockwise (CW) and one counter-clockwise (CCW) rotating prop. Optimized for the Phantom 3, these props features plastic threading--as opposed to metal on earlier 9450 props--producing a more secure hold.
Note: Be sure to replace the original prop with a new one that has the same rotational direction. Improperly installed props will loosen, detaching in flight. For instructions, please refer to your Phantom's User Guide.
