there is a ton of diffrent ways to setup the tail wheel.

one is to tie it into the rudder directly. this is easy to do but might stress the rudder going over bumps

another is to mount the tail wheel and run a pushrod from the rudder clevis to the wheels arm.

I have had luck with a castoring tailwheel (no steering) but unless you have practice taking off with taildraggers you are almost garunteed a groundloop.

I wish I had pics but I am at work now so I cant get to anything.
