Left over from a project are two rudder steering horns for converting an S1 from locking tailwheel to a steerable tailwheel. The horns are made from .08 thk 4130 steel, cut/profiled on an CNC mill and tig welded. The tube o.d. is .845 in. and should fit inside the rudder tube if built to plans.
Price is $45 each and includes shipping in the lower 48.

Hey there.
Interested in buying one of these from you to save me some time but I have a quick question. My Pitts S1 plans show the rudder spar as 7/8” x .035 wall. That makes an inside diameter of .805. Are you positive the outside diameter of your steering horn there is .845?
