Paul: Fixing the wing, where I put my finger through it, was pretty simple. Use a knife to cut out the torn area, back to four areas of balsa. Using clear dope as the adhesive, just put a patch of tissue over the area. Water it down to stretch the tissue, then half dozen or so coats of 50/50 clear dope/thinner. After some very light sanding with 800 grit sandpaper, paint it the color of your choice. If you look at the wing, you can hardly notice the patched area.
See my post # 313.
