209:. The Fury also had a greater interplane gap; because of the stagger this put the upper wing further forward and removed the need for the pilot's cutout. By far the most important difference both visually and aerodynamically was the engine installation, as the F.20/27 had a radial motor, initially the 450 hp (336 kW) nine-cylinder

The upper fuselage was slightly humped, with the pilot sitting in an open cockpit just behind the upper wing, which had a small rounded cutout to improve visibility. A single-axle fixed main undercarriage had its main legs sloping slightly aft from the fuselage and braced back from the axle to the

was considered; but by now the superior performance of the Fury, about 10% faster despite very similar dimensions, shape and power-to-weight ratio showed that the efficiently cowled and low frontal area liquid-cooled engine was the way forward for interceptors.

This description could almost describe the Fury as well as the F.20/27 as the two aircraft were very similar. There were small differences however: for example the leading edge of the tailplane was straighter in the Fury and it had horn-balanced

The F.20/27, sometimes referred to as the
Interceptor, was a clean single-engined, single-seat and single-bay biplane, fabric-covered over a metal frame. The unequal span wings had parallel
