RE: cuttin a hole in a foam wing
I have already cut the foam. I was just wanting to make a guide hole so i can cut the final hole with the hot wire. If the brass tube idea will work, i will try it. I just dont really want to bugger them up, cause 3" foam is about $20 per sheet. Also, is it possible to just fiberglass over the foam, or is balsa sheeting a must?
thanks,
andrew
