Gaps are bad. I can't see what you're working on, but it may be better to just seal the gap with some Monokote and live with it.... lessons learned.

I love Hinge Points though, but you have to inset the pivot point into the control surface. You have to do the same thing with pinned flat hinges too.

I did a tutorial on Hinge Points you may want to look at.
