Much larger than its predecessors, this two-seater helicopter was powered by a more powerful fan-cooled engine located in the nose. Each of the two rotors had three blades made of compressed wood with leading edges in metal. They rotated at 275 r.p.m. and had both cyclic and collective control all enclosed within the hub. A ratchet-type freewheeling device was used for flying in auto-rotation.

The maiden flight took place in Scotland in October 1939, but World War II, then in its early stages, caused all work to be stopped on the W.6 in the middle of 1940.
