Hi Glen

I recall using a Dubro .40 size tail wheel assembly. I installed it in the rudder also, with no problems. Last fall, I failed to pull my Midstar out of flat spin in time. It landed pretty hard, breaking the cheeks and separating the doublers from the firewall and and a former. Additionally, the metal wire for the tail wheel broke between the mount and the wheel. But there was no damage to the rudder. All in all, the repairs were very easy to make. I even got to fly her a few times last month on some luckily pleasant days here. What a tough bird. I better get another in case they discontinue it.

If you want a softer setup, I think Sullivan makes some nice tail wheel assemblies with a spring that connects to the rudder. Or you can make loop in the wire (instead of inserting it in the rudder) and connect a rubber band between it and a hook in the rudder. Just space the hook and loop far enough apart to provide some tension to the rubber band. (Maybe one of the more graphics proficient members here could provide picture.)
