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 late 1940s and produced in 1946 by Czechoslovakian company Moravan, as a basic trainer to replace the Bücker Jungmann and Bestmann. The Z-26 was a low-winged 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 parties. Examples of the Trener were sold to many countries including Belgium, France, Hungary, Italy, Switzerland and the United Kingdom. Some remain in operation in 2014.
The following variants were progressive improvements on the Z-26:
- Z-26 - two-seat primary trainer aircraft. 163 built.
- Z-126 - all-metal wing replaced the wooden wing
- Z-226 - more powerful Walter Minor 6-III six-cylinder engine
- Z-326 - 160hp model with an electrically retractable undercarriage
- Z 526 - with the Walter 6-III six-cylinder engine (equipped with carburetor)
- Z-726 - shorter wing (9.87 meter span), shorter fuselage (7.98 meter length) with two seats. Avia M-137 AZ inverted six-cylinder engine with Fuel injection. All-metal except for fabric-covered aft fuselage. Cantilever low wing with wide-span flaps. Electrically-retractable undercarriage with tailwheeel. Tandem seating.
- Z-726K - variant of the 726 with a supercharged Avia M 337K engine (210 HP) and variable-pitch propeller. Not in serial production
Many sub-variants were also produced, for example the Z-526A and Z-526AFS were aerobatic specials. Production of the Z 26 series ended in the 1970s with the 726.
