Anyone have any advice for installing the elevator and rudder pushrods on the Magic Extra? I just installed mine without connecting the clevises - to see how well they move . I put them together as instructed. But they don't seem to move as freely as I think they should. Especially the elevator pushrods. They aren't binding, but sure feel stiff inside the sleeves. I'm beginning to wish I had connected the two elevator halves and installed one single elevator pushrod.
