Parrot AR.Drone Replacement Propellers
These propellers have been specially designed for the AR.Drone by a team who won the French Army micro drone contest. They are made to optimize power consumption and thrust.    Propellers are marked either “C” (for “clockwise”) or “A” (for anticlockwise). The propellers should be mounted as follow: motor 1: "C" motor2: "A" motor 3: "C" motor4: "A".    This kit includes 4 propellers (2 “C” and 2 “A”), and 8 circlips. For an easy mounting, a special circlip tool is available in the “mounting tools kit” to easily insert and remove the circlips which hold the propellers and the gear on the shaft.
