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]
