I tried a couple of ways to mold the upper trailing edge surface of the wing tip tonight, but was just not satisfied. So I decided to add another 4-bid layup to yesterday's layup. We'll see. Also, I continued closing the inboard end of the aileron and the outboard end of the flap. This requires fitting foam in the ends, followed by a 2-bid layup, ending with a 1/4 inch micro fill. Tonight I placed the foam and 2-bid in the flap end, and completed yesterday's aileron end with the micro fill.
