Zmaj Fizir FP-2

In 1933, the command of the Yugoslav Royal Air Force (YRAF)decided to replace outdated planes with modern school aircraft, for transitional training from basic training to combat. Zmaj Factory designed a prototype biplane, Fizir FP-1, in 1993 for transitional pilot training, but it did not satisfy all the requirements set by the YRAF. As a result, aircraft designers and engineers, Rudolf Fizir and Dušan Stankov, made adjustments to the Fizir FP-1 and so the plane became the, Zmaj Fizir FP-2.

The designers opted for the concept aircraft biplane, although the YRAF preferred an aircraft with one low wing (due to the development of modern combat aircraft). In the end, the concept of a new transitional school aircraft was accepted. Prototype Zmaj Fizir FP-2 (Fizir Prelazni) with a 300 kW (400 hp) Gnome-Rhône 7K engine was completed and test flown at the end of 1933. More test flights followed, and by 1934 the plane showed good results. Zmaj modified the FP-2 during 1934 using a 235 kW (315 hp) Walter Pollux II engine, but the results were not satisfactory.

The Zmaj Fizir FP-2 was a two-seater single-engine biplane aircraft, with air-cooled, 7 cylinder radial engine (Gnome-Rhone K-7 308 kW), and a pair of struts on each side. It had flaps on the upper and lower wings. Landing gear is fixed to a shaft, and deployment uses a rubber rope. Fuselage and wings were wood covered with canvas. The plane represented a classical "Yugoslav manufacturers 'school'" - a two-seater, two wings, solid wood construction and polished aerodynamic shape, easy to fly, stable and reliable aircraft that is largely insensitive to pilot errors.

On 22 May 1936, the Zmaj factory offered the Navy a seaplane Zmaj Fizir FP-2H with a Gnome-Rhone K-9 engine, but the project was not accepted.[2]

A total of 66 aircraft of this type were produced and served in the Yugoslav Royal Air Force from 1936 to 1941. They were used for training military pilots. The first series of 20 of these aircraft were delivered to the YRAF in early 1936 and were immediately introduced into the first and second Pilot School. From 1938 to 1940 45 more aircraft were delivered. All three series aircraft were equipped the same, except the third series of five aircraft that were equipped to fly blind.[3] These planes had a new pilot's panel and Zemun Teleoptik (similar to the Rogožarski PVT). The fifth series Zmaj Fizir FP-2 (15 copies ordered in 1940) was not completed by the start of the April war. At the beginning of 1943 the Germans allowed factory to complete the fifth series aircraft Zmaj Fizir FP-2 for the Croatian Air Force, but by 22 October 1944 (Liberation Day Zemun) only 8 aircraft were delivered. The last 7 aircraft were completed and handed over after the People's Liberation Army Air Force for use by the Yugoslav Army. Thus the total number of Zmaj Fizir FP-2 aircraft produced was 81.
