The Fizir F1V (Физир Ф1В - fizir prvi vojni - first military fizir) was a the basis from which engineer Rudolf Fizir developed a series of single-engined, two-seat, reconnaissance biplanes fitted with different engines. Construction was carried out in the Yugoslav aircraft factories "Zmaj" and "Rogožarski" between 1928 and 1932.
Zmaj built 15 of the Fizir F1V-Wright version 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.
