I think that's where is saw the video on gluing in the hinges. Basically I just modified his way of doing it. As far as the hinge size I used the 1/8th inch size. I notched the control surface at the hinge elbow to allow clearance for the elbow to work and keep the hinge line tight. If your surfaces are covered in monokote and you get some glue where you don't want it, acetone will dissolve the dried glue. If your plane is painted, well just don't get the glue where you don't want it to be. Just make sure that you put the vaseline on everywhere around the hinge hole including the entire trailing edge of the wing and leading edge of the control surface. My rudder and elevators on my pattern plane were both done using my method and they were both painted. It looked good and the hinge line was tight. Just my 2 cents.
