I used an Ohio Superstar Products Medium tailwheel. I got the larger one because I fly off grass. This thing has a ton of ground clearance, and the slightly larger wheels make ground handling a piece of cake. I included pictures of the tailwheel steering, and someone else in that post put in a picture of how they did theirs. I believe after modding this thing like this, it just flies and handles much better. You can really push the envelope with it, and even touch n goes are a little more fun when you don't let the tail settle. It's also a challenge to see if / how long you can keep it on just one of the mains without touching the other to the ground.
