That is a problem. I havea Quicke 500, the orginal design and the tail wheel on it has to be centered after every flight. It will hold up for take off but not landing. It has some sort of post off the rudder through the fuse to the tail wheel. I am second or third owner, so I'm not sure just how it is set up other than it isn't a very good setup. I've seen a stearing arm on the tail wheel that is a pull pull arangement off the rudder, each arm is spring loaded. The issue though is when you can't get the lines back to the stearing arm on the wheel. Something like you are describing is about you only choice other that a seperate servojust for the tail wheel.
