Dear Steve,
The tail hook up is a bit basic, but it sure works. All I did is add a second rudder control horn, to the rudder, and looped wire to connect from the tail wheel stearing arm, to the second control horn on my rudder. I'ts simple, it's easy to dial in and adjust, and it works. Enclosed are a couple of pictures, and if you need more information, just ask.
Soft landings always,
Bobby of Maui
