Comment:
The C-70 which first flew in 1971, is a 15-meter racing class ship of molded fiberglass construction. The fuselage incorporates a tubular- steel framework that ties together the landing gear, wing fittings and a protective cage around the pilot. Differing in a number of respects from the prototype, the production version emerged with a Wortmann airfoil, full-span flaps, no brakes and a conventional horizontal tail. The 90- degree flaps allow a very steep landing approach. The ship also features retractable gear, in- flight adjustable rudder pedals, adjustable seat- back and (optional) 91 kg./ 200 lb. Water ballast. Production ceased in 1974.
