Trainer, two-seater with enclosed cockpit and low wing supported by V-struts. G-20 was ordered by Osoaviakhim for aerobatic training. Wing struts were attached to special pylon, integrated into the canopy and serving as a 'safety frame' in the case of noseover.
It passed State Acceptance Trials and participated in The First Large Circle flight of light aircraft. Engine power was insufficient for 'high aerobatics', and in 1937 G-20 was re-engined. In more powerful configuration it became very popular, and about 70 pilots were trained on single built G-20.
