Mikoyan/Gurevich MiG-3

Exigencies of the times precluding fundamental redesign of the MiG-1 to eradicate the fighter's less acceptable characteristics, a series of what were, in effect, palliatives were applied to the basic design to result in the MiG-3. Power plant and (initially) armament remained unchanged, but some structural simplification and strengthening was introduced. The engine was moved forward 10cm; dihedral of the outer wing panels was increased by one degree; a 250 l supplementary fuel tank was introduced beneath the pilot's seat; the aft fuselage decking was cut down; the radiator bath fairing was enlarged and extended forward; the supercharger intakes were revised; 9mm seat armour was provided, together with radio, and four wing points were introduced for a maximum external load of 220kg. The first MiG-3 left the factory in December 1940, 11 being completed by the end of the month; 140 were produced in January 1941, and, by June, production had peaked at 25 aircraft every 24 hours. The first MiG-3 was delivered to a VVS regiment in April 1941 - simultaneously with the MiG-1 - and production continued until 23 December 1941 with approximately 3,120 built, but 50 more were completed from component stocks in the early summer of 1942. Some MiG-3s had a supplementary pair of 12.7mm BK machine guns under the wings - raising take-off weight to 3510kg - and others were fitted with two UBK guns of similar calibre in the wings. Tests were also performed with two fuselage-mounted 20mm ShVAK cannon.

The UB HMG WoF is about 0.842 kg. unsynchronized for 17.5 rps.

In view of the time between inception and production it was not surprising that the handling qualities were not of the best, espcially when one considers the length of the engine and the demands that made on the overall design. It has been reported that some 2,100 models of the MiG-1 were produced and production of the MiG-3 was several thousand more. However, these planes were no match to the Luftwaffe and it was only the continual bombing of the German homeland by the Allies which required the return of German assets that gave the communists the ascendancy.

Was it the MiG-1 or '3 that had the tendency to stall out in sharp turns?

Yeah, nice 'plane but the longitudenal dihedral didn't help (Short body, in English!)And must have been hard to see past that wing - as Ronald said, multi role /ground attack fighter, it ain't!

While the 360 turn time above was typical, it could range from 22-26.5 sec. With the wing gun boots, firepower was higher but handling became unacceptable and speed fell. The 1.2kg salvo is with the old ShKAS 12.7mm nose gun before the more effective UB 12.7mm replaced it.
The MiG was the lone Russian fighter that was superior at high altitude. Unfortunately that was almost useless on the Russian front.

Weight of fire / sec. salvo = 1.2-1.44kg[-2.8kg].
Climb to 5km = 5.3-6.8 min.
360 turn = 23 sec.
