soviet planes and 4.1x...

[1984]

that interesting and funny, only now i saw this page and found what sometimes i just repeated (with help of peoples from many forums/sites, of course) findings and what written in total by Alex Ruchkowsky...

in fact it's good because 2 similar opinions it's very indicative, we on right way...

highly recommend to read this page, especially, because it's already on english and no reasons to some my bad translations further, i will only add some information and want to focused on armament/performance...

(by the way, in addition to old drawings from 2010 on this site, if DT will do/fix 3d model of laggs, here apparently last and best or one of best - at this moment - drawings for this good deal)...

and just for fun, official report about NS-37, plus, attached some pics, on 1 belt with 20 mm shells for yak (i see 1 AP - 1 HE) and apparently, another good confirmation of belting-theory, belt with 23 mm shells for il-2 (i clearly see 3 AP - 1 HE or HEI)...

oh, and i remembered about one of, apparently, confirmations of weight of yak-9d as front fighter ie around 2900 kg (310 kg of fuel, around 20 kg of oil), well, here interesting document and description of plane for tests with 2880 kg...
