I cut a spruce 1 " thick to the shape of the rudder post. Then I hollowed it out on my mill except for + / - 1/2" either side of the hinges. I made it about 6" longer than the tip of the rudder to the bottom of the fuse. I epoxied a plate in the lower lip of the fuse with a slot for the rudder post. This was a very tight fit and used a jacking screw to get it straight. I had to put the wing on first to get the rudder correct. I did notice there was more curvature on the left side of the rudder than the right. I do have pics and will try to attach them. The importance on the rudder was the jacking screw to precisely move it left or right. Hope the photos help. If you want details email me for specifics. [email protected] Jim
