In 1947 a British Gliding Association design competition, for a two-seat sailplane, was won by Hugh Kendall, Miles' assistant test pilot. It was a side-by-side two seater called the Kendall Crabpot I, with a 60 ft. span and an aspect ratio of 18. A version with a novel asbestos fibre-polymer wing and a wooden fuselage with a butterfly tail was proposed by Miles, but the wing failed under low loads. Elliotts of Newbury built a conventional wooden wing to use with Miles' fuselage. The resulting glider flew, but not well and development was abandoned with just one example built.
