These propellers have been specially designed for the AR.Drone 2.0 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 follows: motor 1: "C", motor 2: "A", motor 3: "C", motor 4: "A".

This kit includes 4 propellers (2 "C" and 2 "A") and 8 circlips. For easy mounting, a special circlip tool is available in the mounting tools kit to easily insert and remove the circlips that hold the propellers and the gear on the shaft.
