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.
