I use mounts now for the tail wheel.

Had the classic rudder mount job on an old Balsa USA Stik. On one takeoff, it lifted off then went into a screaming loop, flew by the club president's head and buried itself in the dirt a yard from his feet. Stress from use had caused the lowest CA hinge on the rudder to break.

Week before, a tailwheel with the same setup had pulled loose and gave one instructor a merry chase down the edge of the flight line as plane castored back and forth.

We passed a club rule next meeting. No more direct connection of tailwheels to the rudder. Springs or shock absorbers required.
