Rick, you can do one of two things. Either glue some balsa sticks to clothespins and attach to the back of your eleveators. Turn them in towards each other and that will give you a pretty good idea of not only center points, but equal travel through entire servo motion. In theory, taking the CRC off one side and putting it on the other elev half should work as well. I would probably use the CRC to center and the sticks to monitor travel. Pauly, I got mine at Central Hobbies.
