Zlin Z-26 Trener

The Zlin Z-26 Trener was a tandem-seat basic training aircraft built by the Czechoslovakian company Moravan.

A low-wing monoplane of largely wooden construction, it was developed into a series of all-metal trainers.

Several were also produced in aerobatic variants, known as the Akrobat.

The original Z-26 was designed in the 1940s and produced in 1946 to meet a requirement for a basic trainer to replace the Bücker Jungmann and Bestmann.

It was a low-wing monoplane of mixed construction, with wooden wings and a welded metal tube fuselage, powered by a single four-cylinder piston engine, the Walter Minor 4-III.

It first flew in early 1947, proving superior to the competing Praga 112, and was declared the winner, entering production in 1948.

Later derivatives were also optimised to participate in aerobatic competitions, and many were owned by private pilot owners.

Both the two-seat Trener and the single-seat Akrobat were considered highly successful, winning several aerobatic awards in the 1960s.
