Looks good, I have been toying around a couple of ideas on the tail wheel attaching a bottom horn to the rudder, could you elaborate on yours? what width did you go with on the horn and tail wheel control.
I was thinking of using the 4130 for the Horn welded to a tube which will fit inside the rudder 3/4" pipe, and riveted in with an two additional AN3 bolts/lock nuts, in through holes.
