Just after the factory tests, on 8 October 1926 pilot
Vladimir Striževski flew the aircraft from
Novi Sad to
Skopje to
Mostar to Rajlovac (
Sarajevo) to
Zagreb and returned to Novi Sad – a distance of 1,410 km – over a period of 8 hours and 40 minutes. As a result of this performance, the aircraft was entered in an international competition of the
Little Entente in Poland where it was one of 14 entries. Though some of the other competitors had aircraft with twice the power, it came in first place. Thanks to this success and satisfactory test results, it was decided to put the Fizir F1V into serial production, but as an intermediate trainer rather than as a reconnaissance aircraft with the result that some changes were made, such as adding dual controls. Difficulties with supplies of the original Maybach engine resulted in a variety of other engines being fitted, from which the individual variants would derive their names. The Fizir F1V was used at the flying schools to transition pupils to reconnaissance and bomber aircraft, replacing the worn-out
Hansa-Brandenburg C.I as production permitted. Twenty examples were produced by the end of the 1928 and 12 in 1929. The Fizir F1V aircraft used by the pilot schools were withdrawn from service and replaced with the new
Zmaj Fizir FP-2 in 1936. Some examples of these aircraft had flown by the beginning of April and were still in use when war started in 1941 as a liaison aircraft or training. Last flight from the family of these types of aircraft Fizir F1M (Fizir first Navy) was a seaplane that was developed at "Zmaj" by Zemun on the request of the Navy Command for a reconnaissance seaplane on floats. Known as
Zmaj Fizir-Jupiter or "Big Fizir" they were used in the Naval Air Force for as a reconnaissance seaplane and for towing targets for antiaircraft training. On one of these aircraft was fitted with an
NACA ring in 1931 to improve the Jupiter engine's cooling and reduce drag. These aircraft flew during the war and three were captured by the
Italians however it is unknown if they made any use of them. ==Operators==
