Same goes for the british aircraft, I'm afraid. Ruskies and Brits are OP, Brits to a lesser degree than their Russian counterparts though. Beaufighter is a good example of that.
And as some forumite said; "Playing Russia is like playing on sandbox difficulty. Brits are easy mode.", and I can only agree. I personally feel the japanese aircraft are worse than just about any Russian or British aircraft, but you know, most players propably feel that way anyhow.
I think it's a problem they will address soon, if not they risk loosing the community.
