I put a Sullivan tail wheel on mine, the one with the spring that goes from the rudder to the wheel (I think its Sullivan), and used the stock wheel. I didn't like the stock tail wheel setup.

For servos I used:

Rudder: Hitec 605 with pull-pull
Elevator: Hitec 605
Ailerons & Flaps: JR 537
Throttle: Futaba 148
