Dick,
I didn't' say it in my previous post because anthof stated he wanted to get away from solder clevises, but I prefer them. I always put the solder clevis at the servo and then I use threaded clevises at the control surface. You were absolutely right, doing it this way give you a great way of adjusting the control rod. If you make a good solder joint when you put it together it'll never come loose. IMHO it's the strongest way of doing it. I prefer these over z-bends because you can remove the control rod from the servo horn without having to take the servo horn off.

Hope this helps.

Ken
