WW was perhaps exaggerating with his "everything but 190s" comment.
I believe he was talking about the entire planeset (including zeros, f4fs, hurricanes, spitfires, etc). In THAT regards, the P51 is below average. But, most US planes are "below average" in turning, compared to the entire planeset. Compared to other US planes? I don't think even YOU can claim the P47 turns better than the P51. You've seen the turn radius chart, with full flaps the P51B matches the P38 for turning with flaps, and the 51D is a little behind that.
Not to mention all the speed/climb/acceleration data I included (secondary to the turn radius, but still a factor in "suck" or "not suck"...
Hey I'm not saying it accelerates like a 163, or that it turns like a a6m2. I'm saying you're incorrect to state it's the worst turning plane in all the late ware US planes, and that it accelerates slowly, and etc etc etc.
I'm not some wild fanatical P51 fan, but I've flown it enough and FOUGHT it enough to know it turns a damn sight better than you give it credit for.
