I forgot that when you make epoxy and microballoons in a large batch, it get hot and shrinks when it cures. My fillets pulled up out at the edges to about 1/8" at the TE. The wing is still true in the saddle. May make a thinner slurry and reset the wing in it to make flush again. I had to do the same thing to FG fuse. fillets. Bellypan tri-stock in place and bottom preped with 5/8" brass tubing.
