The Z-35 Heli-Trener, developed by the Czech Moravan works, first flew in 1960. It was a small, two-seat trainer designed for maximum simplicity of structure and maintenance. Apart from the trainer version, the Z-35 was also offered as a single-seater for agricultural use. The prototype underwent intensive trials up to 1964, but demand was insufficient to justify large-scale production and the project was therefore dropped.
