The 480 hp (360 kW) Bristol Jupiter IV radial engine was entirely enclosed within the circular-section fuselage, with an elaborate arrangement of ducts to channel cooling air over the cylinders.

A large spinner with a central opening to admit air, constructed of laminated wood with internal wire bracing was fitted.

The fuselage, which increased in diameter until the trailing edge of the wing and then tapered to a point, was built around a pair of circular steel frames to which the wing root stubs were mounted: aft of this structure it was a semi-monocoque built up from three laminations of tulipwood over hoops which were braced with radial wires.

The undercarriage was operated by a handcrank and chain drive, the legs being housed in channels in the fuselage and the wheels within the wing roots.

Although the aircraft had been entered for the 1922 Coupe Deutsch de la Meurthe competition, and was allocated the racing number 10 which was painted on the tail, it was not in a fit condition to compete, and although it was suggested that it be used as an engine testbed, its flight characteristics were entirely unsuitable for this role and it was eventually scrapped in 1924.
