Tailwheels.
At the local field, nobody uses the wire in the rudder anymore due to hard landings trying to rip rudders off.
I have added a small basswood plug to the bottom of the fuse and used a simple regular tail wheel bracket (dubro or any other).
Instead of passing the wire up between the fuse and the rudder, bend it back right away so it passes under the rudder. (like the spring wire on the sulivan) Then bend it down into a hook.
A small eye hook is screwed into the rudder and then a rubber band wrapped between the hook and the eye. There is now no jarring to the servos and if you hit real hard and the tailwheel rips off, it breaks the rubber band and not your rudder.
Simple, cheap, and works from the little electric to the 1/3 scale IMAC stuff.
