Development of the AIR-1 with radial engine. At least six vehicles were built(exept AIR-2S). They differed mostly by engines. The plane was built if fact in propaganda and educational purposes.
The first plane was mounted by Cyrrus M-1 engine. (first flight- october 1928, pilot- Piontkovsky) One was powered by NAMI M-23 engine. It had plexiglas canopy covering both cockpits and opening sidewards. But the aircraft was too slow to show advantage of a canopy. In addition engine vibration was above acceptable level.
There existed version with 60hp 'Walter' NZ-60 engine had performance slightly worser (due to engine drag) than the AIR-1. AIR-2 appeared to be the last biplane of Yakovlev.
