That's the ticket, Rob. As long as the tailwheel gear wire runs straight up on the rudder hinge line to the rudder, a simple hole is all it needs, no matter where the elevator is. If you put a 90 deg. bend on the top of the wire going straight back, you can anchor the wire to the rudder by drilling a hole and gluing the wire into the rudder itself.
Wish I had Minnflyer's graphics talents. It's much simpler and easier than I made it sound.
