I had to be more specific. I'm looking for blueprints of russian(USSR) military jet engines - AM, Klimov, RD series, all engines of russian MiG and Sukhoi fighters.
Aircraft Scale Drawings
This last one is from the same site as one of the links above, just a page back so you get more link options
This one's mostly WW2 (at least that's all I've looked at!), but I've ordered three so far (free shipping on three, which made buying three about the same price as buying two with shipping. Go figger. I got the F4U, P38, and ME262) and they're EXCELLENT! http://www.aviationshoppe.com/
