[I do not have this problem any more since using certificate's mod, even vs ace AI (as long as we have aircraft close in performance, like 109E4 vs SpitMkI, 109G/AS vs Yak3 for example).

I wish i could say the same. Just flew P-40Bs vs Ki-27s, and the Ki-s seem like they are equipped with JATO packs, unbelievable zoom climb as well as flat out speed.
Has ALWAYS been a problem w/ the AI
