I suppose Steve Bailey is a noob too...
Okay Stang, name the planes in LW MA that are definitely inferior to the P-51D in a Co-E dogfight?
The only sure thing IMO is the Fw-190. (The Typhoon is another possibility. It slipped my mind. Thank you for the reminder, Motherland. The Typhoon is of course worse in the roll-rate department than the Pony. As for shooting down 190s vrs. Ponys...probably you are better at hitting a snapshot on a wildly rolling and jinking craft than I am.)
and? What else?
I think there are alot of factors. I believe there is a certain amount of "tweaking" in the modeling going on to offset the massive natural popularity that planes with P in front of their name will enjoy. The P-51, according to WWII tests should, but does not in AHII, turn somewhat better than the Tempest. The Tempest turns a smaller circle with both flaps stowed and with flaps out, although in practical terms the P-51 can get its flaps down at higher speeds, allowing in my experience the P-51 to barely turn with the Tempest for a few circles-enough to get a kill, but not a decisive advantage. (In point of fact, the D9 will turn a smaller circle with full flaps. Although this is totally impractical for dogfighting, due to the Doras extremely low deployment speeds, it does show you how funky things are with the Mustang's turn radius.)
I think if the P-51 it were correct, it would be a NIGHTMARE, able to fly forever, go anywhere, catch anything with a slight dive, and to drop flaps and turn with well enough long enough that practically nothing would have much chance of dodging the fifty caliber love. Especially with its view for deflection shots. It would almost demand perking. And this in turn, might be bad for business. Can you imagine average noob signing up for his two weeks, clicking on what amounts to THE WWII plane for most Americans, and seeing "You don't have enough points for that model"? Lead to horrible turnover.
And the P-38 by all accounts was even more nightmarish than the Mustang...
