I used the aluminum channel on mine. Guys who have been flying with them tell me they wear badly and soon. Especially the rudder. Many drill them out and put in bushings. If I were to do it over, I would use steel channel. Steel would weigh more but, not as much as the pushrod ends. Lynn N37LH
I am going to use the new airfoil elevator and rudder. Question is what size of chanel aluminum to use for the hinges? I don't want to get my hinges in a bind. I don't want to use pushrod ends either. (plans built, cost, weight, you know the stuff.) Mark I couldn't get on to your site to look at what you did.
