I hope I'm not the only builder to experience this problem...maybe someone out there has an easy fix. I've attached my wingtips to my wings using #6screws and nutplates, but while I was looking at the finished work I noticed that one wingtip has a flat spot on the bottom (about 6" diameter) and the other wingtip has a flat spot on both the top and bottom (about 4" diameter top and bottom) in roughly the same location, a few inches aft of center.
All of the flat spots are very close to the flange that mounts to the wing. I've tried using a heat gun to smooth it out, but in my attempts to not burn the tips I probably was overly conservative with the heat...hence, it didn't work.
What's the best way to fix this? I made a rib out of 1" thick blue foam and stuck it in there, but I ended up with a "low spot with a ridge in it". Not a good solution. Any help here is greatly appreciated.
Oh, and I did a search for this, but couldn't find a good enough answer.![Roll eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
