||Plans available (2012)
The Platzer Kiebitz (English: Lapwing) is a German amateur-built aircraft designed by Michael Platzer and made available in the form of plans for amateur construction.
Design and development
The Kiebitz features a strut-braced biplane configuration, a two-seats-in-tandem open cockpit with a small windshield, fixed conventional landing gear and a single engine in tractor configuration.
The aircraft fuselage is made from welded steel tubing, with its flying surfaces covered in doped aircraft fabric. Its 7.6 m (24.9 ft) span wing has an area of 18.3 m2 (197 sq ft) and uses interplane cable bracing. Engines from 50 to 100 hp (37 to 75 kW) can be used. The prototype used a 50 hp (37 kW) Nissan 12P automotive engine from a Nissan Micra, but Rotax, Volkswagen air-cooled engines and Sauer powerplants have also been employed.
Even though the aircraft can only be constructed from plans, the Kiebitz has proven popular with builders for the European Fédération Aéronautique Internationale microlight class.
