I have taken a wheel collar, drilled and tapped the opposite side fromt he set screw for a second screw, Instead of short set screws; use two 3/4 inch long screws and then run 2 rubber bands back to the pull-pull control horn on the rudder. Simple spring loaded tailwheel steering. [img]i/expressions/face-icon-small-wink.gif[/img] (you can also use matched ball-point pen springs)
