Soviet fighters and 4.12

[gaunt1]

not correctly:

1. ASh-82FNV (M-82FNV) erly (first) name ASh-82FN (M-82FN, the name ASh - Shvetsov's aircraft engine appeared later)
2. 1850hp - afterburning (n=2500, Pk=1200+-20), 1530hp - nominal (n=2400, Pk=1000+-10), 1630hp on 1500 m (n=2400, Pk=1000+-10), 1430hp on 4550 m (n=2400, Pk=1000+-10).

Yes, I admit I was wrong. I always thought that ASh-82FN and FNV are different engines.

Anyway, the performance figures you written are one of the best sources for LaGG-3/5/7 series, but some of them are for prototypes, like the SN: 39210104 "dubler" (current FM is based on this). Meanwhile I also found these test reports, and one of my friends helped me with russian.

According to him, the figures we need:
SN 37210444, 08.1942 for La-5
SN 39213050, 07-08.1943 for La-5F
SN 39210495, 09-10.1943 for La-5FN

the others are prototypes or low quality versions, (SN 37212383, way too slow) and should be ignored.
Plus, there are useful info about the LaGG-3 series too!
