The Podesva Trener (English: Trainer), also called the Trener Baby, is a Czech ultralight aircraft that was designed by Tomas Podesva and produced by Podesva Air of Uničov. The aircraft a faithful 80% scale reproduction of the Zlin 126 and is supplied as plans, as a kit for amateur construction or as a complete ready-to-fly-aircraft.[1][2]

By April 2018 the company website had been taken down and the aircraft seems to be out of production.[3]

Design and development

Podesva designs and builds reproductions of famous aircraft on a custom basis for customers. The Trener was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing, a two-seats-in-tandem enclosed cockpit under a framed canopy, fixed conventional landing gear and a single engine in tractor configuration.[1][2]

The aircraft fuselage is made from welded steel tubing, with the wings made from aluminum sheet. Its 8.68 m (28.5 ft) span wing has an area of 10.8 m2 (116 sq ft) and flaps. The standard engine available is the 75 hp (56 kW) Walter Mikron IIIb four cylinder, four-stroke powerplant.[1][2]

Operational history

Reviewer Marino Boric described the design in a 2015 review as "a faithful reproduction of the classic aerobatic Zlin 126 aircraft, down to the last detail...The handling of this two-seater is impressive."[2]
