The Aero 3 is a development of the Aero 2 two-seat primary trainer, retaining much of the all-wood structure of the earlier machine, but with a more powerful 185 hp Lycoming O-435-A engine, giving an all round improvement in performance.
Main external feature that distinguishes the Aero 3 from the 2, apart from the engine cowling, is the one-piece blown plastic canopy which replaced the former ‘greenhouse’. Full dual controls are fitted and the front seat can be covered with a hood for blind flying tuition.
Production began in 1957 and it largely replaced the Aero 2 in service with the Yugoslav Air Force. They could be equipped for civil or military use.
