I was able to glue on the I-beam to the trailing edge and trim the foam core in preparation for skinning. The TRIAX fiberglass skin will carry out on to the I beam. I took careful measurements from the right wing that the previous kit owner started and I am doing my best to match those numbers so the wings are as identical as possible. One pic is a shot right down the I beam as I was waiting on the 5 minute epoxy to cure. That is pretty flat/straight down a 14" ish run!!. The I beam isn't quite long enough for the entire trailing edge, so I glued a small piece of scrap wood to the end of the outboard end to give the cloth a smooth transition like the rest of the TE. some of this will get cut off when I start to install the winglets. I find I have a much higher level of confidence as I progress. I had the I beam taped, marked and glued up and weighted down in just over an hour this time. On the other wing I bet I spent 5 hours over thinking it and then doing it! I will start filling in seams and gaps and sanding everything today and hope to skin it this weekend. Also, added a second VHF antennae so there is one in both wings for redundancy. I think that is the first time I had t use geometry since high school in 1988!
