RC Plane tail wheel hinge

I wanted to upgrade my 1200mm wingspan Depron Piper Cub with a steerable tail wheel. The idea was to introduce as little force as possible into the rudder. The hinge is only glued to the fuselage, not to the rudder.
I drilled the hinge with a 2mm drill needle so that the 1.5 mm wire fits in with sufficient play.
The wire is both hinge bolt and wheel wire. It is bent 180° at the top and inserted into the small hole. The lower edge of the hinge must at last be adapted to the shape of the rudder.
Maybe you can remix it for your own purposes.
