I have "completed" my wings. I left the bottom skins un-riveted because 2-3 years from now when the fuse is complete, the engine is installed and I'm buying the panel (and auto pilot) -- There will be some new servo, gyro, toy etc. that I need to install in the wing.
Everyting is ready to rivet, just waiting on what technology will do while I finish the rest of the plane.
