RE: 86" Yak
Gorilla Glue.. Now that is an interesting idea. I started with the Pacer hinge glue per spec but I was able to pull one out after it should have cured on the first control surface I completed so I moved back to epoxy. I was curious about the gap space inside the hinge slots, but Gorilla Glue expands as it cures and sounds like it might be a good alternative as long as it doesn't expand out so far that it effects control surface deflection.
