fixed tail wheel or castering tail wheel
I had a castoring tail wheel in a sig LT25. It was a real handful to taxi in a cross wind. I used to have to taxi it by giving it quick bursts of power to get airflow over the rudder. Of course the plane was so light it was back and forth like a drunk coming back in after a flight!
Try it both ways, if the castoring wheel is too much, you can always lock it with a drop of glue.
You might also consider running a sulivan control rod thru the bottom of the plane from the opposite side of your rudder servo to the tail wheel and turn it that way.
Good luck.
