I was considering using 1/32" ply for roots to provide the flexibility but prefer lite ply if it will bend sufficiently. A small circle of 1/8" lite ply can be used to provide thickness (1/4" total) for blind nuts. With the 1/32" I'd need 1/8" lite ply rings to support the tube at the roots as well and likewise on the anti rotation pins.
Thanks, David
How much flexibility do you need?
I think I would keep the root straight and just add balsa filler to fit the curve. As long as the area of the blind nut fits tight tot he fuse that would work.
Take a look at the rear of this stab, you can see the skins extend past the root. Probably toughened up with some ca on the inside I would guess.
