Polikarpov DI-2

poli-di2


Essentially a slightly scaled-up two-seat derivative of the I-3, the DI-2 was powered by a similar 750hp BMW VI 7,3 engine and possessed a similar structure. Armament consisted of two synchronised 7.62mm machine guns and two guns of the same calibre on a Scarff ring in the rear cockpit. Flight testing of the DI-2 commenced in 1929, but early in the programme the horizontal tail separated in flight as a result of flutter and further development was discontinued.
