Widewing,
I agree with most of your statements about the F6F/F4F comparison. The one statement that I disagree with is the one about the speed differential not being substantial. That would be true, if you consider a difference of "only" 50 mph in top speed to be trivial. The difference in AH would be even greater if the flight model of the F6F wasn't porked. Most sources for the Hellcat's top speed routinely repeat the erroneous flight data recorded before the air-speed system on the Hellcat was redesigned to give a more accurate reading. There are a number of sources, reliable sources, that give a corrected top speed for the F6F-5 as being over 405 mph. Even Chance-Vought, Grumman's top competitor for Navy contracts, recorded the -5 Hellcat's top speed as being over 400 mph. I recently saw a reprint of Jane's Fighters of WW II that listed the -5's top speed as being 405 mph.
I find it extremely difficult to get the Hellcat's top speed above 360 mph in level flight in Aces High. It's flight model is almost 60 mph slower than the similarly powered P-47, an aircraft that is just as big dimensionally and weighs a ton more. While the P-47 is undoubtedly faster at high altitude (near 30,000 ft) because of its supercharging, the Hellcat is definitely capable of reaching 400 mph at its rated altitude of 20,000 feet.
HTC has done a tremendous job developing Aces High. However, the requests that I and others have made that the F6F's flight model be upgraded seem to have gone unheeded. But, I'll keep asking. Politely.
