My cables have gone slack after a half dozen or so flights, and I've left them that way. I can't hear the rudder over the aileron and elevator servos buzzing. Perhaps I'll try it right now since the wings and tail are off....

Nope, no buzzing at all. I lifted up the back so the tailwheel is off the ground. No buzzing at neutral. Moved right, moved left. No buzzing when it comes back to center.

Night,
Don
