In 1958 Jerry Smyth began the design of a monoplane sport aircraft, intended to be easy to build and fly as well as stressed to +9g for aerobatics. Construction of the prototype began in January 1967, taking two years to complete. Smyth's first component-built was a hand-carved wooden control stick grip which he said he built the plane around .Plans and kits for homebuilding were made available. Constructed of welded steel tubing with aluminum skinning, the Sidewinder has all-aluminum wings and is stressed to ±9g ultimate loading to allow aerobatics. Engines can be fitted with power ratings from 90 to 180 hp. (67 to 134 kW), weighing up to 310 lb. (141 kg), enclosed in a fiberglass cowling. A sliding canopy covers the cockpit, the landing gear uses some landing gear components from the Wittman Tailwind and conventional controls are fitted but with an all-flying tail plane for pitch control. An unusual under-fuselage spoiler is used for approach control. The original design shared the same windscreen as a Thorp T-18. The prototype attended the 1969 Experimental Aircraft Association convention at Rockford, Illinois, winning the Outstanding Design Award. Currently the rights to the Smyth Sidewinder are held by EU-Wish, which continues to market the design. 290 sets of plans had been sold by 1972, with at least 46 examples registered and flying\ General characteristics • Crew: 1 • Capacity: 1 • Length: 19 ft. 4 in (5.89 m) • Wingspan: 24 ft. 10 in (7.57 m) • Height: 5 ft. 5 in (1.65 m) • Wing area: 96 sq. ft.
