 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.A total of 66 aircraft of this type were produced and served in the Yugoslav Royal Air Force from 1936 to 1941.
