Building a Kadet Sr ARF right now, as a taildragger from the getgo. I'm about 20hrs into this thing and have maybe another 5 hrs to finish.
For the tailwheel, I drilled a hole down the rudder hinge line, and inserted an "L"-shaped music wire down through it to act as a torque rod. Up top, it is tied to the bottom of the rudder.
I have the Electric Kadet and the larger arf also. I plan on making the large one a taildragger.
The small one is set up as a taildragger, but with a skid in the rear instead of a stearable wheel. I used the same method described above to add a stearable tail wheel to mine. Only difference is that I mounted the wheel directly on the rudder controlled wire at the bottom of the plane. Took about one minute to make the mod when building it.
The same thing could be done on the senior, but the pull pull set-up may work better on that size.
