I never used Robart hinges yet (always used CA and never had a failure). All the info here is quite educating however there are still not answered questions here:
Has anyone used hinge pockets? How to install them (to make sure the hinges are aligned properly)?

Other unanswered question here was: "How many?".
I'm building 85 span wing for Edge 540, and every aileron is 36 inch long, 4 inch wide. Aileron is 1 inch thick at the hinge line. I planned to use 4 hinges (1 about 2.5 inch from each end and additional two 10 inches apart). Is it enough?
