Not just P-40 devotee's fly the P-40. I'm flying it lately, but thats just because I need to push myself. Went from the high preformance LW planes, to the MW planes (P-51B, FM2, 109G2, 190A5) and now I'm on the EW planes.
Point is that if it was a bit faster and could climb a bit better then (IMO) it would see more use. I shot down a spit XIV with it just last night, pilot was floatsup. To amend my earlier post on the P-40's turning abilities, I was able to keep with the spit 14 for short periods before he started pulling ahead of me, we were both low E and his engine power probably helped him in the turning.
