It had a large area aerofoil on each of its single wing bracing struts which could be rotated together or independently to give lift or drag.

It evolved, by progressive reduction of the lifting strut, into a conventionally braced parasol wing monoplane.

There was a deep and wide curved cutout over the cockpit to increase the pilot's field of upward view and broad-chord, long ailerons.

This end was pivoted to a triangular, transverse steel frame within the fuselage which also carried the cabane at its upper vertex.

The large, open cockpit was under the wing cutout, with an effective Triplex windscreen and a prominent, faired headrest which also enclosed a parachute.

The horizontal surfaces were mounted at mid-fuselage, though the tailplane was vestigial, more like a long fillet which carried large, balanced elevators with curved leading edges.

Its undercarriage was fixed and conventional, with a pair of faired-in, wood and ply inverted L-struts on either side carrying a rubber cord sprung steel single axle, fitted with large diameter wheels.
