In the first pic you can see the cutouts in the wing I made for the flaps. Again I used a router. Then I used a combination of 17 gram carbon fiber veil and 1.5oz glass cloth applied together in one operation. The carbon veil was stiffer than the glass and it didn't lend itself well to forming around the leading edge and tip, so I used saran wrap to keep the layup in place as the epoxy cured.
