I just completed this conversion. I used a sullivan tailwheel and threaded the rod through the horz stab and up into the vertical stab. Let me tell you, this was a pain the arss mainly because i had to create a "z" bend to connect the wire into the rudder and you have to do this while the wire is already threaded through the horizontal stab. Then the hole I drilled in the horz stab wasn't large enough to allow adqueate travel of the tailwire, so I had to enlarge the hold and then reinforce with with CA and Epoxy. The CG was also pushed back a 1/4 inch so that now it balances at 4 1/4" instead of 4" from the leading edge of the wing. It might be slightly tail heavy when fuel gets low, but it's still within the acceptable parameters of CG based on the instruction manual. I'm confident a little down trim should be take care of it.

I only did this conversion because my engine was returned for service for the past three weeks so I had some time to mess around with it. If I were to do it again, I'd go the additional servo for the tailwheel route and Y connect it to your rudder servo. I haven't flown it yet. I think it looks a lot better as a taildragger, but i'm not convinced it was worth the effort. In my opinion, better to go with an Ultra Stick if you want a taildragger.
