[1][2] It was a pusher design, reminiscent of the Royal Aircraft Factory F.E series, for example the FE8, with a full fuselage replaced with a pod or nacelle with the cockpit and the engine behind it, the empennage supported on an open frame.

Four booms ran rearwards from the wings, two on each side converging in the vertical plane from the inner interplane struts to the tail, with rectangular bracing to stiffen them.

The Zephyr flew for the first time with Paul Bulman in control on 3 September 1923,[1][2] with just over a month before the start of the Lympne Trials on 8 October.

It was certainly later than intended, for the Zephyr had been registered as a competitor in the Vauvilles (near Cherbourg) Light Plane and Glider event which ended on 26 August.

[5] However, by this time the Aero Club had designed and built the much more modern looking Hurricane, a cantilever monoplane with less air resistance and slightly lower weight, though no lightweight.
