As for the wing, I would start by covering the bottom of the wing first. I would cover the entire wing in 4 sections, Cut one piece big enough to completely cover half the wing panel on the bottom side, then cut another piece to cover the other half of the bottom side. Then flip the wing over and cover the top in two separate pieces just like the bottom. Minn Flyers probably got some good graphics somewhere but I havent found they yet.
