[edit] Design and development
The M-2 was designed as a trainer aircraft for the Polish Aero Club in newly created construction bureau of WSK Mielec factory. Main designer was Stanisław Jachyra. The first prototype was flown on 26 June, 1958 (registration SP-PAC), the second on 13 September that year (SP-PBA).
The plane had quite modern, all-metal construction, but its drawback was an imported inline engine Praga Doris, causing vibration and not fit to aerobatics, what limited aircraft use. It was considered to fit the plane with the Polish flat engine Narkiewicz WN-6, but it was only in development stage then (eventually it was never perfected). Due to problems with engine choice, works upon the aircraft delayed, and in a meantime, te Polish Aero Club changed its preferences to aircraft with a tricycle landing gear and withdrew its interest. As a result, the plane did not enter production and further works were abandoned. A development of the M-2 was PZL M-4 Tarpan, with a rectractable tricycle landing gear.
[edit] Survivors
The first prototype (SP-PAC) is stored in the Polish Aviation Museum in Kraków (disassembled), the second prototype (SP-PBA) is preserved as a monument in Radomyśl Wielki near Mielec.
