Design and development

The Apollo Fox was derived from the Aeropro Eurofox, which itself was a metric adaptation of the Denney Kitfox. The Kitfox in turn is a derivative of the Avid Flyer.^[4] The Apollo Fox was adapted to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules. It features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear or optionally conventional landing gear and a single engine in tractor configuration.^{[1][2][3][5][6]}

The aircraft fuselage is made from welded steel tubing, while the wing is built with aluminum spars and ribs. The fuselage and flying surfaces are covered in doped aircraft fabric. Its 9.15 m (30.0 ft) span wing is supported by V-struts and jury struts and features Junkers-style ailerons. Standard engines available are the 64 hp (48 kW) Rotax 582 two-stroke, the 80 hp (60 kW) Rotax 912UL and the 100 hp (75 kW) Rotax 912ULS four-stroke powerplant. The cabin width is 110 cm (43 in).^[1][3][7]

The aircraft's wings fold for storage or ground transportation and can be folded by one person in ten minutes.^[7]

Operational history

In 2003 a 100 hp (75 kW) Rotax 912ULS-equipped Fox was flown by Andor Kántás and Csongor Lathky from Sármellék, Hungary to Sydney, Australia, a distance of 25,000 km (15,534 mi).^[1][3][7]
