4 propellers for Parrot AR.Drone 2.0 Elite Edition
These propellers were designed specially for the AR.Drone 2.0 Elite Edition by the winning team of the microdrone competition organised by the DGA (the French Defence Ministry's armament agency). They were designed to minimise the motors' power consumption while providing maximum thrust.
The propellers are marked “C” or “A”. The “C” propellers turn clockwise, whereas the “A” propellers turn anticlockwise. They must be assembled as follows: motor 1: “C”, motor 2: “A”, motor 3 “C”, and motor 4: “A”. The motor numbers correspond to the numbers of the tubes on which they are mounted. These numbers are indicated under the central cross.
