This video is numbers intensive and pretty hard core, it's not for everyone. However, if you want to know how to calculate sustained turn performance in WW2 fighters, this is the video for you.

IMPORTANT UPDATE. One viewer, ASJC27 who says he is an aerospace engineer, and I believe him, has made some excellent points in the comment section. He says that it's just coincidence that best climb speed happened to be about equal to best sustained turn speed, and that it could be quite different. He says that best turn speed will actually happen where the aerodynamic G load limit meets the power G load limit, in other words where the lines cross. That makes total sense to me and I think he is right.
This doesn't really effect the calculations I did in this case, and has no effect on the math, or relationships of the 47B to 109F, but it's a highly relevant comment. All that said, I have nothing to back up ASJC27's comment, but I do think he is correct. He also make an incredible chart for the P-47 in the John Boyd style.
