Hi Tilt,
>Infact Gudkov was the 1st to bolt the Ash82 onto the Lagg airframe but he used the cowling and exhaust/intake straight of the Su2 without modification...........
After the end of the series production, the MiG-3 was developed into a radial-engined fighter, too.
The first prototype, called I-210 and powered by the M-82A , flew first in December 1941. It turned out to be inferior to the original MiG-3.
External and internal aerodynamics of the I-210 had to be reworked with the help of Tsagi, and the new M-82F was fitted in the improved I-211, which after its first flight in 1943 and subsequent combat trials of 10 pre-series aircraft was considered a success.
However in 1942, even before the I-211 had flown for the first time, MiG was ordered to turn over their research to Lavochkin, who obviously was much quicker to get it into series production with the La-5. Apparently, the leading-edge slats of the La-5 were based on the MiG I-211, too (at least according to Belyakov/Marmain, "MiG - Fifty Years of Secret Aircraft Design").
