In 1947 a British Gliding Association design competition, for a two-seat sailplane, was won by Hugh Kendall, Miles' assistant test pilot.

The wooden Crabpot was not built as designed but developed in two forms, differing in their wing construction.

The design included an experimental wing from by the plastics division of F. G. Miles, Ltd., built from a phenolic/asbestos fibre material stabilized with a paper honeycomb, the manufacturing technique being based on the vacuum moulding process pioneered by the Royal Aircraft Establishment at Farnborough.

[1] The new wing also had a different section from that of the Crabpot, a laminar flow 6- digit NACA airfoil rather than the original 5-digit one.

After he ended his test flying career, he joined Shell-Mex & BP as technical liaison with the aircraft industry and airlines.
