The Bailey-Moyes Tempest, is an Australian-American high-wing, strut-braced, single-seat, microlift glider that was designed by Bob Bailey of Florida, United States and produced by Moyes Microlights of Waverley, New South Wales, Australia.[1][2][3][4][5]

Design and development

The Tempest is a development of the Advanced Aeromarine Sierra and was designed to be towed aloft behind an ultralight aircraft.[1][2][3][4][5]

The aircraft's 42 ft (12.8 m) span wing is made from aluminium tubing covered in Dacron and is supported by a single lift strut on each side, plus a jury strut. The fuselage is made from fiberglass and features a canopy that is hinged on one side for cockpit access. The cockpit is 22 in (56 cm) wide. The landing gear is either a monowheel gear or, optionally, bicycle gear.[1][5]

Although very light, with a standard empty weight of 200 lb (91 kg), the Tempest does not qualify under the US FAR 103 Ultralight Vehicles regulations as a hang glider, neither is it foot-launchable. When it was available the aircraft was supplied as a kit, that required an estimated 200 hours to complete, or as a complete ready-to-fly aircraft. In 1998 the kit was US$10,000 and the complete aircraft was US$12,500. Twelve were reported as flying by the end of 2001.[1][4][5]
