Spud, What servo did you strip? Probably because you were maxed out on your throws. You should always leave a tiny bit left for safety sakes.
The UCD does some of the best knife edge couplings you can imagine. Why would you want to change it? But if you must, I use about 5% up elevator and 5% left aileron. This is a good starting point. I can't get it completely out. And many times I just fly it and use my skills to adjust. Normally about the time the plane is so far away I can't see it is when I gather it back in and get control of it.
I'll have to try the wax job. Sounds like a time saver. This is such a great thread. So many tips.
Oh, I was flying during my lunch hour today. My rudder came off. It was kind of an annoyance. Oh well, I'll pull out some glue tonight and make it better. But tommorrow I'll fly something else till my knees quit shaking.
Thanks,
Barry
