Hmm, P-40 can be a difficult plane to fly - especially for a newbie like me (I've only been at it for a little more than a year here.) The first plane I got kills in was the C-205. Reasonably fast, can turn some, and decent canon with lots of ammo. The two things I have discovered as a beginner are: altitude and speed. Yes, there are those who can kill when low and slow, but I am not one of them. Do NOT climb up to the enemy. If you find yourself low and slow, get out, climb, gain speed and come back. Chenault told his pilots do not turn with the zeros in the p-40. Come in with altitude, speed, then dive. If you have a shot, take, but otherwise, pull up, rinse and repeat. Sort of like a porpoise. (Also classic boom and zoom.) I don't know if that will work here, but I would treat all spits, f6fs and the like as zeros.
