Remarks: on display at Mid-Atlantic Air Museum, - (George G. Spratt (1904-1998) designed this roadable aircraft which featured an earlier version of his Controlwing System. Powered by a 60 hp Mercury 983 cc outboard motor boat engine it was flown for the first time in mid-1973. Primarily a composite structure of polyurethane foam and glass fiber, the aircraft featured foldable wings for towing or storage, non-retractable tricycle landing gear of which the nose wheel was designed to attach to a trailer hitch for road towing. The engine was subsequently replaced by a modified Surabu engine.)
