Yesterday I put on the tail fin. The one from the 'N' kit was just the right size, so no problem there. I then cut the lower wing sections from the wing stock and sanded them to shape. I then used a straightedge and a Sharpie to mark the rib lines, and a round sanding stick to make the indentations where the dope causes the fabric to shrink between the ribs. I then realized that I had a kit with the correct chord, so I stole those wings and cut them to the same shape. Then I had to putty in the ailerons. Then I realized that the ribs on that plane were uneven, and the 'BB' ribs were evenly spaced. I finally ended up using the original wings I had made myself. Oh well...
