Histoire résuméeBiplace d'entraînement pour performances moyennes, construction mixte. Fuselage coque en métal léger, ailes en bois. Adapté à la formation de début à l'acrobatie.

The Z-03B Ifjúság was developed from the Z-03A utilizing the operating experiences of the latter. The prototype first flew at May of 1956. The modifications affected the front part of fuselage. Both seats became more comfortable. The role of the glider broadened as it was suitable for blind flying instruction. This version had no better luck than the previous one. During a demonstration flight the prototype was overstressed. After a repeated stress analysis had been done and smaller modifications had been executed further 32 gliders were built between 1956 and 1959. One glider was exported to Austria.
The Z-03B Ifjúság was a middle-wing, tandem two-seater glider with mixed light-metal-wooden structure. The wing was positioned a bit lower than that of the Z-03A. It was certified for cloud flying, basic acrobatics and spins.
The Z-03B was not an ideal basic trainer due to its high take-off mass and wing loading. Because of the lack of flaps the instructors were reluctant to let the students perform landings. The landing gear was damaged frequently. The glider was withdrawn from operation in 1960 similarly to the Z-03A type due to the unfavorable results of fatigue tests performed at Aircraft Department of the Technical University of Budapest.
