The Flitzer Z-21 or Staaken Flitzer is a British amateur-built aircraft, designed by Lynn Williams and produced by Flitzer Sportplanes of Aberdare, Wales. The aircraft is supplied as plans for amateur construction.[1][2]

In the late 1990s, it was also marketed as plans and in kit form by Bell Aeromarine of Leicester, UK.[3]

Design and development

The Z-21 is a single-seat, open cockpit 1920s-style biplane with fixed conventional landing gear with spoked wheels and a single engine in tractor configuration.[1][2]

The aircraft is made from wood, with its flying surfaces covered in doped aircraft fabric. Its 5.5 m (18.0 ft) span wing has a combined area of 9 m2 (97 sq ft) and ailerons on the bottom wing only. The aircraft was designed for the 65 hp (48 kW) Volkswagen air-cooled engine, but other variants have been developed that use a variety of engines, including the 110 hp (82 kW) Rotec R2800 radial engine.[1][2]

Further planned developments include a tandem two seater, a four aileron version and a lighter weight version.[1][2]

Operational history

In August 2014 there were eleven Flitzers registered in the United Kingdom.[4]
