I use Gorilla Glue to sheet the wings and stab. I apply the glue to the sheeting and then use a foam roller to spread the glue out as well as soaking up any extra. I align the sheeting on the cores and the cores lined up with the shucks. Then I use weights to hold the whole thing down until it cures. Once everything is dry, I pull the weights off, but I leave the wings in the shucks. I sand the extra sheeting off using the shucks as a guide. Once all of the edges are trimmed, pull the wings and stabs out of the shucks, and presto, you have flying surfaces.
