Performance data for VVS aircraft?

Thanks for the links.

Those are all pretty good resources but as far as I've seen they have no polars/other charts which is what I'm looking for.

Primary sources as they say.

I've got what appears to be tests by the germans on captured Klimov 105 and 107 engines, and a Soviet Chart showing the same.

I've also got some Russian charts showing climb rate and max level speed plotted against altitude.
