Hello Jester:

I have a Sullivan tail wheel (10-15 lb version) and it works great. First trim back the covering. Cut a piece of 1/8" or 3/16" thick plywood just a bit wider than the tail wheel plastic base. Use the left over yellow covering and iron onto the plywood bottom side. Make sure the opposite side of the plywood is not covered. Drill and mount the tail wheel with blind nuts. Then drill and countersink the exposed screw and nut portion into the bottom tail section. Epoxy it it place. It will never come off. I used the larger spring to hook onto the rudder. I fly on a grass field and have many hard landings without any problem. Also, the Sullivan tail wheel has a much higher profile than the stock wheel. I put some prebend in it to lower the tail. The Sullivan wire is also larger than the stock wheel hole. I need to enlarge the holes in the tail wheel and the wheel collar.

I do not use a pull-pull rudder servo system. Just make sure you have high torque servos on all control surfaces. I move the battery and throttle servo all the way forward inside the cowling, so that I do not have to add balance weight. Keep it light.

Hope it helps
