190's: I've learned that if you get them slow, you better know what you're doing. Keep it fast, but please don't turn it into a BnZer for I will hunt you down

. 190, IMO, is an E fighter.
P-51: Defenitly an E fighter, but can turn fight if needed (with a notch of flaps if needed too do so). P-51 love speed and, sometimes, even turn with a spitfire when at high speeds. If you see a "Braunco Mustang" on, ask them for advice on the P-51.
P-40: Truely an excellent plane. It's not the fastest, not the best turner, can't outrun much, not the best at getting it's speed up, but it's only plane that I canthink of that balances everything so nicley. Good firepower, good top speed, good turner (both high and low speeds), just a great dogfighter. It's also the one out of the three that requires the most practice in, mainly because everyone goes after the P-40 first.
