Trimmed the right wing tip back edge 1/4". This seems to be universally needed by all the build logs I have read. Once you trim it there is not much meat to the rear seam so I added a couple latyers of fiberglass and epoxy resin to beef that rear seam back up. The left tip will need the exact same trim / reinforcement After thet, sanded the seam and put n a layer of spot putty to help fill the pin holes.
