Speed is life. Both in AH and in real life. It was a common "truth" in the 30s that biplane fighter were superior to monoplane due to better turn performance but the reality showed that speed is everything. With speed u can dictate the terms of fighting. Only reason for us to have zekes and Brewsters is that it doesnt cost anything to get killed so people in faster planes give away their advandage and engage in turn fights with them. (then complain when they get shot down). A good pilot in a bad plane will loose against a good pilot in a good plane. And good = fast. For ex [insert good pilots name] will never kill a 190d in a brew unless the 190 allows him to do it. On the other way around he can kill a Brew in a 190d without needing to wait for a misstake from the brewster pilot.
