|Z-126 Trener II|
The Zlin Trener is a family of aircraft that was based on a basic training aircraft, the Z-26.
The original Z-26 was designed in the 1940s and produced in 1946 by the Czechoslovakian company, Moravan 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 Z-26 variants were 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.
The following variants were progressive improvements on the Z-26:
- Z-26 – two-seat primary trainer aircraft. 163 built.
- Z-126 – introduced in 1953, Czech military designation C-105, all-metal wing instead of original wooden wing.
- Z-226 – more powerful Walter Minor 6-III six-cylinder engine, C-205
- Z-326 – Introduced in 1959, with an electrically retractable undercarriage (standard on future models)
- Z-526 – with the Walter 6-III carburettor's six-cylinder engine
- Z-726 – with Walter M 337 supercharged engine.(used in Romania by sportive aviation with M-137 Sh engines under the name Zlin-726 Universal).
- Z-726K – Improved version.
In 1956, deliveries began of the Z326 Trener-Master and Z326A Akrobat. Many sub-variants were also produced, for example the Z-526A and Z-526AFS were aerobatic specials. The production of the family was terminated in the 1970s with Z-726. The Z-726 Universal had reduced wingspan.
