Zlin Z XII

The Zlín Z-XII, a Czechoslovakian two-seat sports aircraft, marked a significant design milestone for the Zlínská Letecká Akciová Společnost (Zlín) aircraft manufacturing company.

This triumph came after the company’s inception in Otrokovice, following its acquisition by the renowned Bata Group.

Designed by Jaroslav Lonek, it was a low-wing monoplane constructed entirely of wood.

In April 1935, two prototypes, each fitted with a distinct engine, were revealed and subjected to thorough testing.

The Z-XII, equipped with a Zlin Persy II engine delivering 33/35 kW (44/47 hp), was recognised as the superior model.

Its successor, the Z-212, featured a Walter Mikron engine and provided an option for either an open cockpit or a cockpit hood.

This model was in high demand and was exported to many countries.

Production of the Z-212 was conducted under German oversight after the occupation of Czechoslovakia.

The German Luftwaffe operated Z-XIIs and Z-212s until 1943, with around 20 Z-XIIs being assigned to Slovakia.

After World War II ended, the Americans seized a Z-212 and repurposed it for sightseeing flights.

Another Z-XII, which had been disassembled into parts in Otrokovice, survived the war.

It was later reassembled and flew again with the registration OK-ZJD.

In total, there were 201 Z-XIIs and as many as 58 Z-212s produced.
