RE: Building the BUSA SPAD 13
More progress on the wings. I took your advice Jim and added the slight scallops between the ribs. The shear webs on the spars between the ribs adds a lot of strength. Also the paper tube makes it easier pulling the servo leads to the center section. This completes the first phase of the top wing. The bottom wing is straight forward as the top wing with a couple exceptions. The landing gear mounts to the bottom wing and the dowels are in the rear and the wing bolts are in the front leading edge. Just a little more work on the bottom wing for the first phase of construction.
