Stal-MAI

Development and design

The Stal-MAI was a low-wing cantilever monoplane with a two-spar trapezoidal wing and a braced empennage. It was powered by a single Mikulin M-34R liquid-cooled V12 engine equipped with a gearbox driving a variable-pitch propeller. The retractable landing gear was operated manually. The two-seat cockpit was enclosed by a single canopy. Except for the fabric-skinned control surfaces, the aircraft was made of steel. The Stal-MAI was among the first aircraft in the world to be constructed mainly out of steel.
