RE: ZN Line Xigris Build Thread
Now I went back to the wing to place the root rib. This is included in the kit and has three holes, two for wing attachment and one for the adjuster socket. The sheeting overhangs the root a little bit so it takes a bit of shaping of the root rib prior to installation to ensure it fits.
I placed 1/4"-20 nylon bolts through the root rib and CA'd them in place. Then I counter sunk the foam a little where the head of the nylon bolt will sit and finally used polyurethane to attach the rib to the foam/sheeting. Care needs to be taken to ensure you are holding the rib down while the glue is expanding, some balsa pieces help here.
Sand the overhanging sheeting flush with the rib when its setup.
