As originally built, the helicopter featured a two-bladed rotor, and was powered by a centrally located Bentley engine which drove four-bladed pusher propellers on each blade.

A pyramidal structure acted as the mount for the engine and the blades and rotated, as a single unit, around a vertical axle.

Sited below that structure was a small streamlined fuselage, containing the pilot, and an undercarriage that consisted of four landing pads mounted outboard on struts.

One test flight in October 1925 ended when a rotor blade touched the ground, causing considerable damage.

[2][4][5] The project was discontinued in 1926 when the Air Ministry withdrew funding, with them preferring to focus further rotary wing activities on craft like the Cierva autogiro.
