Rivet the trailing edge. Yesterdays comments were really for today. Once I got the trailing edge riveted it came out straight and true. One down and one to go! I purposely built the left aileron first. I have been working on the right wing and knew that if I built the right aileron first I would put the left one off until later. Since I knew that the ailerons didn't need to be matched to the wing I could build both at the same time. Otherwise I would just move to the flap and build it next. This way when I start the left wing it should go much quicker.
