I wanted to draw attention to another issue that is worth looking at.
R_Target has done some very good research (as far as I can tell) on the F6F and it's top speeds. It's been long held in my head (and based one some preliminary tests) that the F6F was a little on the slow side. Target has gone and done some good research and has some specific numbers:

It's definitely on the slow side and not by a little bit. Worth looking over the data.
