InterPlane Skyboy
The InterPlane Skyboy is a two-seat, side-by-side, high wing, single engine, pusher configuration ultralight aircraft that was manufactured as a completed aircraft by InterPlane Aircraft of Zbraslavice, Czech Republic. Design and development. The Skyboy was designed in 1992 specifically for the German market as a trainer. It was adapted for the US FAR 103 "Ultralight Vehicles" category for use as a two-seat trainer under the FAR 103 trainer exemption. It later became available as a US light-sport aircraft. The aircraft is available in Canada as an Advanced Ultralight Aeroplane. The Skyboy wing is  built from aluminum extrusions for the spars and wing ribs and covered with doped aircraft fabric. The wing's leading edge is Mylar covered in fabric, to increase stiffness. The wing is supported by "V" struts and utilizes jury struts. The fuselage is built upon an aluminum main tube that runs from the tail right to the rudder pedals. The wings and horizontal tail surfaces can be folded for trailering or storage. The cabin is constructed from two fibreglass shells, joined together. The rear of the cabin is covered in aircraft fabric. The optional cabin doors open upwards. Controls are  conventional three-axis. The control stick is a centrally mounted "Y" stick, between the two seats that can be used from either seat. The Skyboy has a distinctive main landing gear, consisting of a trailing idler link, with suspension consisting of a coil spring mounted over a shock absorber. The company describes the main landing gear: "one of the best landing gears in the market (makes bad landings look good)". The available engines include the Rotax 582, Rotax 912, Rotax 912S and the Jabiru 2200. The Rotax 503 was available at the beginning of production, but did not provide adequate  performance. The Skyboy has never been available as a kit aircraft, but only as a factory-complete, ready-to-fly product. Labour wage levels in the Czech Republic have meant that its price has been generally similar to buying unassembled kits for North American buyers. In 2008 the completed Skyboy base model sold for about US$60,000. Operational history. Aside from its flight training and recreational aircraft roles, the Skyboy has been employed in South Africa for surveillance duties, in Australia for professional aerial photography and in Mexico for tourist sightseeing flights.
