Design and development
Based on the Prue Two, the IIA incorporates many changes to the basic design, including a T-tail in place of a low-tail, fixed instead of retractable landing gear, a shorter two-piece wing instead of a three-piece wing and an empty weight that is 210 lb (95 kg) lighter. The Prue IIA was built by Minghelle between 1961 and 1964, culminating in a first flight in October 1964.
The Prue IIA was used to set several multi-place glider records. It held the world out-and-return record of 366.88 mi (590.44 km) for a period of six months in 1967. A second world out-and-return record was set in 1972, flying 425.3 mi (684.5 km) from Pearblossom, California. In 1967 it was also flown to a world multi-place declared goal record of 322.35 mi (519 km).
