i know not so much about these things, and it's not really important, but someday need include in game other planes with skis, like yaks, laggs and il-2s for winter 1941-1942...
for example, attached from
here, lagg-3 around 8-1x series with skis, rockets and racks for fuel tanks/bombs...
even don't know, how much worse these planes, apparently, fights with lw was mainly excluded...
