Ronnie, I used this one, a [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXFV47&P=0]Sullivan Tailwheel[/link].

I cut the tail open (saving the piece) and put a hard block in the inside, then glued the piece back on. Mounted the tailwheel to that and have been using it as a free spinning, didn't want to get into hooking it up. i guess you could if you ran a 2/56 rod down from the rudder, or bent up the little springs that come with it. and no luck on pictures yet, still tryin! good luck,

Ron
