Just finished my LT 40 that I made into a tail dragger as well. What I did was to mount a tail wheel bracket to the end of the fuselage bottom. The trick is to route the control rod/linkage to the opposite side that controls the rudder. In other words, I run the rudder and tail wheel steering off the the same servo. The rudder exits the fuselage as per the plans and the tail wheel steering exits the bottom side of the fuselage on the opposite side. The wire for the tail wheel runs up through the bracket and is them bent about 90 degrees. I wish that I could send you a drawing to make this more illustrative. You have to do it this way (opposite sides) to make the rudder and tail wheel directional. the one thing that you have not addressed is the position of the landing gear. I used a preformed alum. bracket instead of the wire that came with the kit. It provides for a much stronger and less flexible main landing gear. Finally, I hope that you moved your landing gear center forward. A good rule of thumb is to put the main wheel axle about even with the leading edge of the wing. This also helps with moving the CG forward since the aircraft tends to be tail heavy. I'll try and think of some other pit falls.

Good luck
