MerlinL14 is right you could probably get by with a non steerable wheel. If you really wanted wheel control, I would mount a tailwheel bracket or even a brass tube off the end of the fuse, and run your tailwheel wire up through the bracket and through a hole in the elevator hinge joint into the leading edge of the rudder. Bend the wire at 90 degrees and secure behind the rudder control horn plate. This will give you much better leverage on the tailwheel and take all the strain off the rudder. I just completed this mod on my Kadet. The only difference is my kadet fuse is a little different but your mod should be even easier.
