This set includes 4 propellers total: 2 red (1 clockwise and 1 counter-clockwise), and 2 black (1 clockwise and 1 counter-clockwise). Directionality of the propellers is important. Propellers with an ‘F’ on the underside indicate a clockwise (CW) propeller, and propellers with an ‘R’ indicate counter-clockwise (CCW) propeller. Replace your old or damaged propellers to make sure your CoDrone EDU flies and hovers properly. This set includes 2 red propellers for the front, and 2 black propellers for the rear.
