Martin & Wilkinson Cadet III
Another motorised version of the basic Cadet/Tutor airframe was the Slingsby/Martin Motor Cadet Mk 3, which was a T31B Tandem Tutor acquired from the Dorset Gliding Club in 1970 and converted by P. J. Martin and D. R. Wilkinson at Twinwood Farm aerodrome, Bedfordshire, to have a 1,600cc Volkswagen engine in the nose. It was now a single seater ultra-light, the front seat being replaced by a 6.5 gallon fuel tank, and a Luton Minor's undercarriage was fitted to give airscrew clearance.
Registered G-AYAN and named ‘Thermal Hopper', the sole Cadet Mk 3 received its Authorisation to Fly on 15 January 1971.
Engine: VW 1600cc
