I built two of these wings. They fly very well. Take of at a very speed. Laminating around the leading edge was very difficult. The solution I found was to first wrap two narrow strips of glass around the leading edge, and then sandwich the wing between fiberglass. I used four layers on both sides and two more strips around the fuselage mounting area. I used a clothes vacuum bag and a vacuum cleaner to compress the laminated wing until the epoxy cured.
The yellow wing has less anhedral and an airfoil with a slightly flatter bottom. Can share that one if anyone is interested. I printed that one using the fuzzy skin feature of Cura so that epoxy and PLA bond better.
