Wow, 180 page thread. That'll test how much I care.

Like all threads, by the time you get to the last page there's a link to a guy that makes horns that don't even roll to 90°, let alone 180 or 360°. I see a fabrication problem, solved either by 3D printing or a welded seam between rolled rings.

*On the diffuser thing,some wheel fairings are showing up which are longitudinally flat-walled on the inside and contoured on the outside.
There's virtually zero info on this so far,but if it's chosen over inner-contoured fairings,then there might be a scientific reason for it.
On my VLVW design, the front wheel pants cant outward (ahead of max camber) and the rear wheel pants cant inward (to follow the tapering Template).

*From M.I.T.'s solar work,it looks like whatever we do,the side wall of the diffuser/wheel fairings should be blended to mitigate hook-vortice formation-induced intersection drag.
AKA filleted?
