I converted a 60 size one after it was built as a nose wheel plane

I mounted a Dubro 60 size tail wheel bracket on a piece of 1/4" maple ply with the pivot center line the same as the rudder hinge line.
I made a new wire then ran through the elevator to the rudder and was epoxied into the rudder.

I turned the rudder all the way to one side and drilled the hole

I was able to bend the wire 90 degrees after I stuck it up through the elevator and insert it into the rudder with the rudder unhooked from the servo and turned to the side. It has worked without trouble for several years.
