From what I read the Russians liked the quality build and finish of the P39. If you throw the Russian P39 aces in with all the Allied Aces a bunch of them will end up at the top of the list.
Ive been flyin the 39Q in game and it isn't so bad considering what you are up against. I just wish the 37mm had a higher rate of fire. It feels like it holds it E decent. The D seems a bit more fragile. I threw it into a 500 mph dive once and it broke!

I even got Bozon flying a "obsolete" <his word hehehe> P39 the other day! He seemed to of enjoyed the big cannon!

Huzzah!!!!!!!!!!!!!!!
