I scratch built a Kadet LT-40. The tail wheel gave me a big headache because of the rudder location. I purchased a Sullivan Tail Wheel Bracket. It would not work but it did give me ideas. I finally made my own tail wheel assembly. In the picture the vertical wire is cut above the collar. The horizontal wire is attached to the rudder. The assembly is easily removable.
Planning ahead in case of problems, I added a hatch on the bottom of the fuselage for access. The opening is covered over now. I can cut the covering and add the hatch when needed.
