The Hall Ibex is an experimental, American, gull winged, single seat glider that was designed by Stan Hall and first flown in 1968. [1] [2]
The Ibex was designed by Hall to investigate the reduced wetted area of the pod and boom configuration, hands off spiral stability of a gull wing, and the low speed performance of wide NACA slotted flaps. It also features a V tail, 135 lb (61 kg) of water ballast and a 15 m (49.2 ft) wingspan to comply with FAI Standard Class rules. [3] On one of its first flights the Ibex showed significant tail flutter. Initially Hall considered replacing the tail with a conventional empennage and tail [4] but ended up moving the ruddervator counterweights from the tips to the roots which eliminated the problem. [5]
The Ibex was still flying in 1980 and was eventually donated to the National Soaring Museum. [6]

General characteristics
Performance
The Göppingen Gö 3 Minimoa is a single-seat sailplane produced in Germany. It was designed by Martin Schempp and Wolf Hirth and was produced the year after their first glider, the Göppingen Gö 1. It first flew in 1935. The name is derived from the name Moazagotl given to lenticularis clouds caused by the foehn wind in Sudetenland. The name was used for one of Hirth's earlier gliders and since the Gö 3 was a smaller version, it was called 'Mini' as a diminutive.
The Schleicher ASW 15 is a single-seat sailplane designed in 1968 by Gerhard Waibel and manufactured by Alexander Schleicher GmbH & Co. The ASW 15 has shoulder-mounted wings and an all-flying tailplane, with its single tow-release placement a compromise between winching and aerotowing. The later ASW 15B had several improvements, including a tow-release placed on the plane of symmetry, an 11 cm taller rudder, a slightly larger main wheel, and the provision of a 90-litre water ballast system.
The Briegleb BG-12 is a single-seat sailplane of wooden construction developed in the United States in the 1950s. It was marketed for homebuilding in plans or kit form, with over 350 sets of plans selling by 1978. The BG-12 is a conventional sailplane design, with a high cantilever wing and a conventional empennage. Later models featured a highly revised fuselage, a swept-forward tail fin, and an all flying tailplane with balance tabs.
