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 retractable tricycle landing gear.
Metal construction low-wing monoplane, conventional in layout, metal covered. Semi-monocoque fuselage. Trapezoid wings, two-spar, fitted with flaps. Crew of two, sitting in tandem, under a common canopy, with double controls (student in front, instructor in the rear). Fixed conventional landing gear. Flat engine in front, two-blade tractor propeller, 2.3 m diameter. Fuel tanks in wings - 120 l.
