the N was specialized long-range version designed specifically for service in the Pacific theatre. nothing more.
Anyway you can better marginalize a fighter that could fly 12 hour missions, faster than a D model, and hit just as hard? The November was, technologically, close to the pinnacle of piston fighter development during WWII. Ergonomics, autopilot, simplified engine controls, etc. Sure, a lot of stuff that makes no difference in AH2, but significant none-the-less.
same engine as the M, but tuned and propped for maximum range, not performance.
Wrong. There's no such thing as "tuned and propped for maximum range". You can fly for maximum range, but the powerplants were the same and performed the same. The basic difference between the two aircraft were weight, airframe, and fuel capacity.
the N is not competitive in no real sense at all when compare to the other aircraft it shares the 5ENY pool with. Its acceleration, climb, maneuverability are all below average to poor, put next to an LA7, Tempest, hog-4, spit16 and 14, it looks downright pitiful. Someone who REALLY knows what they are doing, and how to pick their fights can do pretty well in it, but calling it competitive is silly. Competitive rides can be flown with at lease some degree of success in the MA by novice pilots, the N cannot.
Sour grapes. Just because its not easy doesn't make it non-competitive. I'm not going to change your mind, so I won't try. I guarantee if you started a poll, most folks that have been around the game for more than a few months would consider the N-Jug competitive in the air-to-air MA.
the M was the pinnacle of P47 development, superior to the N in every conceivable way except range, and would make a far more attractive ride under typical MA conditions than the N ever will. It would be to the P47s what the -4 is to the Corsairs.
I won't disagree that the M would be more competitive in the MA. But, it was not the pinnacle of P-47 development--it was merely an up-engined P-47D.
Climb rate of 3,700 fpm
460mph at 28K
400mph at only 10k
it hauled its fat bellybutton around pretty well.
And will still get shot down in the MA when it gets low and slow, just like a November Jug.
