10/31/2008. Remarks by Ray Watkins: "VZLU Zlínská Letecká Akciová Spolecnost (Zlín Aviation Co. Ltd) was established by Bata Ltd (better known for their shoes) in 1934. After WW2 the Czech aviation industry was nationalized and Zlín at Otrokovice was renamed Moravan Národni Podnik (Moravan National Corporation, also known as Moravan Otrokovice), although its products were still referred as 'Zlín' types.

The XZ-35 Heli-Trenér (Heli-Trainer) was a light two-seat training machine designed by Jan Mikula and first flew in 1960. The aircraft was constructed of aluminum and the 140 hp Walter M332 engine was mounted in the nose of the cabin. The Z-35 was also offered in a single-seat version, with a chemical hopper in the port seat position, for agricultural use.

A small number of prototype and pre-production aircraft were produced, and testing continued until 1964, but due to insufficient demand the project was terminated."
