The AR Drone 2.0 Genuine Central Cross is the rigid central structure of the AR.Drone. It is supplied already assembled, made of tough PA 66 high grade plastic with 4 x carbon fibre tubes, plus 4 x motor mounts.
Three types of screws are used in the AR.Drone. The one with the slices are used to attach the main board and the navigation board on the body set. The longer screws secure the motor’s electronic controller to the central cross and the shorter screws secure the motor itself on the central cross.
