I double checked my measurements then cut out the notch for the counterweight. Next I cut the end of the aileron skin. My tip ribs don\’t seem to fit right but this seems to be a common problem. I\’ll continue with the second skin then work on the tip ribs. I\’ll probably have to make new ones. I hope I don\’t have to build the whole plane twice 8^D. I completed about 90% of the layout for the second aileron skin.
