Righton was a farmer from
Ruawai in
Northland, New Zealand. In 1931 he had been granted a patent for a variable incidence wing design. Design of his glider is believed to have begun in the early 1950s, with construction lasting through to the late 1960s. The glider was a cantilevered
parasol-wing monoplane of conventional configuration, notable for its large wingspan of . The incidence of both the main wing and the tailplane could be adjusted in flight. The fuselage was a simple slab-sided design and had a box-like cross-section. A long boom, extending from the nose of the glider, was fitted with a movable
counterweight, allowing the glider's
centre of gravity to be adjusted in flight. ==Operational history==
