The Fizir F1V was the basis from which engineer Rudolf Fizir developed a series of single-engine, two-seat, trainer/reconnaissance biplanes fitted with different engines.
The prototype was first flown in late November 1925 by test pilot Vladimir Striževski.
Further development of the basic Fizir design was undertaken with the assistance of Dušan Stankov resulting in the construction of five additional prototypes and the delivery of 32 production machines designated Fizir F1V over the next three years.
While these had been built at the Rogožarski factory, Zmaj built 15 of the Fizir F1V-Wright versions and 5 Jupiter-engined Fizir F1M floatplanes for Naval Aviation in 1930.
Zmaj was also responsible for conversion of several Fizir-Maybach trainers to Lorraine-Dietrich engines in 1932, which extended the service life of these machines under the new name Fizir-Lorraine 400 hp.
