|Histoire résumée||The BJ-1|
After the IWW, Patrick BEATTY returned to South Africa, and started Performance Sailplanes, with the idea to produce gliders locally. A licence was obtained to manufacture the Grunau Baby. Unfortunately, the hoped-for local market never materialised, and only one Baby was produced. In order to survive, commercial wood-turning work became the main activity of Performance Sailplanes.
Soon after the Grunau Baby was completed, Pat BEATTY and Fritz JOHL teamed up to design a world beating glider. The 'BJ-1' was designed in 1953, and the designers were confident that it was going to be a world-beater. Like all subsequent designs, the BJ- 1 was designed for South Africa's strong thermals - it had a very high wing loading for its time, and was equipped with trailing edge flaps to improve low speed flying.
The BJ-1 was never completed. Soon after the construction process started, the two designers came up with an even more radical design, the BJ-2.
