Here is a cool idea. At the average pump angle, which is higher than you’d expet, put a foil shape in the cross section to optimise the flow over the fuse.
I would be interested in seeing the various cross sections across the brands at the same sliced angle. This is super interesting. I vividly rememeber the first time on a Code 850s after the AFS Silk 850v1 mono and the feeling of more turbulence. I am now used to it and don’t notice it, but I wonder if this might play into it.
I do think some part of how awesome the F4 foils are is related to the very small fuselage profile. The CODE is pretty chunky, which I guess is also a good thing if we care a lot about durability.
I’ve often felt that the fuselage probably doesn’t have to be as stiff as they are now, but I haven’t had the means to try making a few different smaller profiles to see if a little flex is an issue.
I agree that more care could be given to the profile of the fuselage, but it seems to me that overall profile size is the first challenge
I setup a quick app where you can compare the cross section of various foils
Eg below which is a rough stab at the Code cross section.
Crispfoils explained the angle mechanism but what I’ve ended up on is no doubt super naive approach, but you can replicate his foil shape as per the second screenshot
