I've now decided that my plane will never need a floptube and am leaning towards switching back to a fixed fuel pickup. I figure I'm supposed to open the tanks anyway for the safety wire thing, so I may as well do it. However, it's been so long since I built them I can't even remember what the differences are. Obviously I would relocate the fuel sender back to it's original location and close the hole in the rear baffle with a solid plate. I seem to remember some hinges, trap doors, and guides that should be easy to put right. As for the actual removal of the flop tube itself, what should I use to plug the hole in the nose of the inboard tank rib? Any other advice would be great.
