| Description |
This helicopter is commonly considered to be the first practical helicopter. It used both flap and lag hinges. The blades were tapered and resembled modern blade design. The co-axial helicopter had yaw control (by allowing pitch difference between the two rotors). The blades were controlled in cyclic pitch by using a swash plate design. It held the duration record of 42 minutes, and a distance record of 27 miles (44 km).
