High wing braced passenger monoplane. Cockpit and passenger cabins - enclosed, door at the port side of the fuselage. 'Stal-2' was built at OOS GVF as a result of wielding experiments with different steel alloys. Aircraft frame was formed by quite complex 3D structure of thin-wall wielded profiles of corrugated steel. Despite being very labour intensive and costly, such airframe was twice lighter than equivalent wooden or thick-wall tube structure, and aircraft normal payload 43% of takeoff weight.
Flight trials started on October 11, 1931, less than a year after the creation of OOS. No problems were revealed, and Stal-2 was put in production at just built aircraft factory N°81. Novelty of technology caused 'slow start', and series production started only in 1934 (87 aircraft).
Total 111 Stal-2 were built, all powered with 300hp Wright J6, M-26 or MG-31 engines. Stal-2 and its successor Stal-2 proved itself a good light passenger aircraft. One Stal-2 was equipped with landing flaps and designated Stal-2bis.
Production of Stal-2 was phased out in 1935 in favour of Stal-3.
