Definitely do NOT use the stock CA hinges!!

I had read about several failures after I had already built and flown my Showtime several times. Then, one day, one of my elevators separated from the stab. The plane was acting funny so I decided to land it, and it became VERY unstable when I took the power off to land. When it came in the elevator half was still attached by the control horn but all the hinges were gone.

Use Robarts or similar.
