It took about 3 hours to build the rudder. I started with two pieces of 1/4 inch triangle, with some 1/32 inch ply as spacer between the hinges. I used Klett hinges because I intend to make the rudder removable for easier shipping. The triangle stock makes a nice bevel and the 1/32 inch ply give a nice straight surface for the wire through the hinges.

Also pictured is a 1/8 inch light ply piece, along with a half piece as a spacer for the front wing screw. This keeps the fuselage from distorting while tightening the wing retaining screw.
