Jim,
When I said "humming" I meant rattling of the wire or playing like a guitar string when the engine is running. The system is totally quiet at neutral. I might add the JR pull-pull servo brace if it still cold tomorrow!
I also forgot to state that I first reduced the mechanical advantage of the rudder by going a hole in on the servo arm.
The O-ring is not very tight on the wires and just acts like a damper.

Hi Eric,
After I sent that message I guessed that you were referring to the rods vibrating. Of course if one ran them through teflon tubing like the elevator rods that would take care of the problem.
Don't you get in trouble if the servo arm lengths aren't the same length as the rudder control horns in a pull -pull system?
I also noted that you moved the control horns up near the mid-point on the rudder which is a good idea. Did you have to add material inside the rudder and how did you do it?
I assume Troy suggested control line cable that isn't supposed to stretch. Did he have any other good suggestions?
Always trying to learn, Jim O
