... seems very strong. is it modelled using 150 avgas?
:uhoh

lol
P-47M has the same engine as the N model with D40 weight, it should feel strong.
(AFAIK)
-
At typical MA altitudes performance is roughly the same as a P-51D...for five minutes, at which point it becomes roughly the same as well...a Jug.
M performance is not too far ahead of what P-47Ds were already doing with 150 octane when the M arrived however.

July 24, 1944, 70" MAP was cleared for use by Jugs with the B series R-2800. When tested at 70", it translated into 444 mph @ 23,200 feet. The test aircraft was a P-47D-22-RE Razorback. More powerful B series engines in later D models may have resulted in a bit more speed.

Huh...just eyeballing those figures seem to be within 10mph of what is listed for the 47M between 10 and 23K, although the M is significantly faster right on the deck in-game. Interesting.

What I also found interesting was a note associated with the original charts for the P-47D-10...
"Climb performance of Curtiss 836-2C2-18 propeller and Hamilton Standard 6507A-2 propeller was nearly identical, the difference between the two being within the limits of experimental accuracy. A definite difference of performance in level flight high speeds was found, with the Hamilton Standard propeller giving from five to eight miles per hour faster speeds throughout the altitude tested."

That sounds like the pitch range of the Hamilton Standard was slighter better at the high speed end by perhaps just a degree or two, giving slightly better top speed performance. When they were both operating well within the pitch range limits, i.e during a climb, they were similar.
