The Z-35 Heli-Trener, which was created by the Czech Moravan works, made its inaugural flight in 1960.
This small, two-seat trainer was designed with the utmost simplicity of structure and maintenance in mind.
The hover test flights conducted on the Zlin Z-35 prototype demonstrated its considerable success; however, it became evident that a more potent engine was imperative.
Consequently, the integration of the larger, six-cylinder Avia M-337 engine mandated the unsightly protrusion in the aircraft’s nose, leading to the designation of the revised design as the Z-135.
The prototype underwent rigorous testing until 1964.
Unfortunately, the entire Czech rotorcraft research program was terminated due to a decision made by the Warsaw Pact, which mandated that Czechoslovakia focus on building jet trainers.
The Z-35 was to be used as a Military Helicopter trainer and Air Ambulance.
