He indicated they were built to plans and I've never heard or seen a KR with piano hinges in the tail surfaces. I have nearly 400 hours now on my "standard" KR tail surfaces with aluminum hinges. They are nowhere near worn enough that I'm thinking of major surgery to rebuild them. I agree with several other posts and suggest that if the tail is finished I'd finish the airplane and go fly. If you are still flying the airplane after hundreds of hours of flight time and they need attention, do a rebuild then. At that point you'll know more what you want anyway. Anyone looking to "bush" the original hinges use caution. There is not much excess metal in the hinges to be enlarging the holes for bushings. Larry Flesner
