De Havilland D.H.85 Leopard Moth

Introduced in 1933 as a successor to the Puss Moth, the de Havilland D.H.85 Leopard Moth bore a superficial resemblance to the earlier aircraft but incorporated a number of major changes, not the least of which was revised fuselage construction. The steel-tube structure of the Puss Moth was replaced by the spruce and plywood box which was becoming a de Havilland standard, providing accommodation for the pilot, and for two passengers who were seated side-by-side in the rear of the cabin. New tapered and foldable wings with swept leading edges were fitted, and the main landing gear upper shock-absorber attachment points were relocated. The prototype made its first flight on 27 May 1933 at Stag Lane, and just two weeks later won that year's King's Cup Race at Hatfield; two similar aircraft finished third and sixth. This auspicious start ensured commercial success, and three years' production, initially at Stag Lane and then at Hatfield, totalled 132 examples.
