I was going to measure it for you this weekend, but it turns out both are covered at http://www.n56ml.com/kcontrol.html ...1/4" OD for the internal one, and .75" for the other. At the time I built my dual stick setup, I thought .75" seemed "about right" to me on the one from the stick torque tube to the bellcrank, but now that I know how little force you can actually generate on the stick without ripping the wings off, I'd say 5/8" is fine. I probably should have calculated it and realized that it would be some crazy number like 900 pounds of force, but at the time I had much bigger fish to fry than to get wrapped around that axle, and I'm still in that boat. I don't think that last sentence qualifies as a mixed metaphor, but there are three of them twisted in there...
