I did what I am calling the standard test for now: 30# 15” out the foil measured 26” from the fuse on the mast. Some interesting results, one new test is I measured the fuse (Axis black regular only because the square shape made it easier) at the mast AND right behind the foil. About a third of the flex “in the foil connection” came from the fuse twisting. And M6 takuma beat Axis at that measurement, which I would not have guessed, IDK if my foil-tape job is why? Anyway spreadsheet below, if you do the test please plug in numbers. It would be cool to get enough to make graphs. Nerd Alert!
Yes, I love to borrow when I can….I’d love to test a carbon lift fuse for twist.
