I have a Flip 3d that I am getting ready to test fly. I bought it already assembled. On the way home, the metal wing bolts vibrated loose just riding in the back of my truck. I did not have the wing in, just the bolts through the blind nuts. I know with the wing on, it would stop some of the rotation in the bolts, but would I be better off with nylon bolts instead of metal? I am not worried about them shearing off, because its a 3d plane and would be a wreck way beyond repair before the nylon sheared. I just wonder what would hold the wing on best.
