haha thanks Jim I may try these hinge pocket things out so I can remove the tail surfaces for mx and etc. I made a modification to my kit built 60 size extra where I ran a piece of music wire through the hinges that I could remove the aileron by just pulling the wire out. I havent modified the other aileron to mirror that one until i get a few more flights on it to see how I like it. I like the idea of being able to remove the surfaces easily though.
