I felt it necessary to reinforce the wing tip with .025 6061T Aluminum to have more for the rivet to grip. I bond this in with J B Weld, which held very well, however, this added a bit more weight than I would have liked.
I also wired the fuel sender and completed the fuel line installation.
I'm often asked how you put a plane together and my frequent response is with duck tape, the photo attached is proof positive this is true.
