The Z-35 Heli-Trainer, developed by the Czech Moravan company, embarked on its maiden flight in 1960.
This compact, two-seater trainer was crafted for maximum simplicity in both structure and maintenance.
The Zlin Z-35 prototype’s hover test flights showcased its significant success, yet it soon became clear that a more powerful engine was necessary.
As a result, the incorporation of the larger Avia M-337 six-cylinder engine necessitated an unsightly bulge in the aircraft’s nose, which led to the new designation of the modified design as the Z-135.
Testing of the prototype continued intensively until 1964.
Regrettably, the entire Czech rotorcraft research program came to a halt due to a Warsaw Pact directive that required Czechoslovakia to concentrate on producing jet trainers.
The Z-35 was intended for use as a military helicopter trainer and air ambulance.
