Keep in mind during the build to use a shaft or somthing to link the rudder down to where the tail wheel will be so it will steer. Alternately you can us a pull pull system off of the rudder servo to steer the tailwheel with. I have my Tiger's tailwheel freewheeling as the thread broke for my pull pull set up. it works, but if there is any wind taxiing to the runway and back to yourself and the pits is out of the question.
