None of the aircraft handle like the older models, imo. First, HTC correctly modeled the E more closely (no WEP), and the C (old B) now has a DT and 500lbs bomb available. The C too is a bit more lively on the controls. The F seems to be the race horse. Even though it is the heaviest of the P40's, the Merlin engine really pulls it along nicely. The F also seems to be the most lively at mid to higher alts. The N has better WEP performance down low, but it doesnt last long.
Vs LW aircraft, if the pilot can keep his wits about him and maintain its E and not get into a blatant turn fight or out n out run-n-gun fight it will be fine. I like both the F and the N for high speed attacks, but the urge to immediately re-engage the target has to be tamed since the P40 needs all the alt and speed it can get. Oddly enough, without looking it up, I think most of my victims have have been targets that I've been able to out turn at high speeds (zekes, etc) or aircraft that I've been able to match in a dive because I was able to hold my me long enough to get the guns in them.
IN short, they are good but not for the inexperienced or real eager players. Patience, intuition, and proper ACM will carry the day for a crutch plane it is not.
