I converted mine a few years ago. Added a small chunk of light ply to the bottom of the fuse. Bolted on a Sullivan tailwheel mount. I had to melt the solder on the button of the Sullivan mount and turn it 90 degrees. Bend a piece of the spring wire into the shape of control horn with a small hole to accept a clevice. Solder this into the hole of the button. Build a control rod, one end to the rudder servo and the other to the tailwheel. That looked easiest with the plane built. If the plane is not built, I would go another way.
