[AR Drone 2.0]Screws
Three types of screws are used in the AR.Drone 2.0.
The first type, the one with the slices, are used to attach the main board and the navigation board on the body set.
The second type, the longer screws, are used to secure the motor’s electronic controller to the central cross.
The third type, the shorter screws, secure the motor itself on the central cross.
