I have continued working on the rudder and the Vertical stabilizer. There are actually 3 sections to work on, the forward piece of the vertical stabilizer, the middle flat pieces that fit under the forward piece and attach between the 2 vertrical spars, and finally the rudder itself. The rudder is attached via a piano hinge on the starboard side of the aft spar. The bottom is cut inline with the bottom of the vertical stabilzier, and the top supports the counterweight that extends from the top of the rudder forward over the hinge line toward the front of the stabilizer. So, here's where I had to re-do the top of the rudder. The bottom of the rudder needed to be cut on an angle, but matching the top surface of the aft fuselage and the bottom of the vertical stabilizer. I cut it at a wrong angle. When I realized my mistake, I devised a plan to lower the rudder, re-cut the bottom angle, and add a small section to the top of the rudder. I bent another piece of aluminum, fit it on top of the rudder, riveted it in place and attached the rib and the counter weight to the top. Worked like a charm. I will monitor for any problems during flight testing. See pictures for details.
