The design is "a fantasy one-of-a-kind design, not a scale" replica, but is intended to be similar to a First World War fighter.[5]

Design and development

The aircraft features a strut-braced biplane layout, a single-seat open cockpit, fixed conventional landing gear and a single engine in tractor configuration.[1][4]

The aircraft is covered in doped aircraft fabric. Its 20.5 ft (6.2 m) span wing has a total area of 146 sq ft (13.6 m2) on both wings. The prototype was powered by a 64 hp (48 kW) Rotax 532 with the newer 64 hp (48 kW) Rotax 582 two-stroke powerplant a builder option. Uniquely, for ground transportation and storage, instead of folding wings the aircraft features a removable tail section.[1][4]

Operational history

The design has won many awards, including Arlington Champion 1997, Oshkosh Honorable Mention 1997, Arlington Grand Champion 1999, and Oshkosh Reserve Grand Champion 2002.[6]

As of December 2007 one example had been reported as having been completed and in April 2015 only one was registered with the Federal Aviation Administration.[2][7]

A two-seat Myfyter II was planned and one example reported built, powered by a Geo Metro four stroke engine, although the company does not currently market it.[1][2][4]
