Some of that stuff is still a state secret in Russia.
Maybe Oleg has a source in the archives somewhere - probably a good idea to check the IL2 forums,
at least I have seen a Yak-3 in the air and heard comments about it. (Duxford)
You can get "State Secret" information here (32Mb pdf, 114 pages)http://rapidshare.com/files/197153284/Fighters_VVS_RKKA_1930-45.pdf.html
can anybody translate it?
re; the Yak 3Ms out there flying, as far as I know they use Allison V 1710s for their powerplants, so not much data from them being of use I think,
The only one I've ever seen has a R-2800 bolted to the front, so again, probably not a great example, although we could argue whether or not it was an improvement
can anybody translate it?some good comparisons with the 109 in the final pages
