Prior to World War II Taylorcraft was known for producing two-seat in tandem basic trainers and to meet demand it developed what became known as the “Tandem Trainer”.

This series of ultra-light aircraft was initially built in Switzerland as the Neukom AN-20B and AN-22 and was produced during the 1980s.

The prototype of the Model 15 “Foursome” (NX36320), powered by a 112-kw (150-hp) Franklin 6A4-150-B3 engine, was flown for the first time in 1946.

The SP-55M is a redesign and developed variant of the Yakovlev Yak-55 and has been built and marketed by Technoavia in Moscow and, like its predecessor, has been a popular aircraft around the world for competition in Unlimited Category competitions.

In 1936 the Taylorcraft Aviation Company was formed by C G Taylor, a former President and Chief Engineer of the Taylor Aircraft Company, to produce the Model A, a two seat light aircraft.

The Team Airbike, also known as the Ison Airbike, was designed to meet US FAR103 regulations and has been produced in single and two-seat variants, the latter being licenced as an ultralight trainer or as an amateur-built aircraft.
