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.
The aircraft is made from wood, with its flying surfaces covered in doped aircraft fabric. Its span wing has a combined area of and ailerons on the bottom wing only. The aircraft was designed for the Volkswagen air-cooled engine, but other variants have been developed that use a variety of engines, including the Rotec R2800 radial engine.
Further planned developments include a tandem two seater, a four aileron version and a lighter weight version.
Operational history In August 2014 there were eleven Flitzers registered in the United Kingdom.
