go to nmpra.org and look for the links at the bottom of the home page. Thier are 2 great articles on Skinned hinges. I think they are easier to do than regualar hinges if you are glassing the wing anyway. on a monokote wing use #600 scotch tape and make a "wiper" by putting two pieces of tape together. sticky side to sticky side. Leave half of the sticky side exposed on one the bottom and cut the sticky side off on the top. Some use clear office dividers and the tape to make the wiper. Kind of hard to explain in a post.I tried to take a picture of mine but you cant see the tape[

] Maybe some one else has a picture.
