Wing

There are both two wing halves drawn on the building plan, so you can assemble them simultaneously, if you want to. Pin the tapered balsa trailing edge 3 to the building plan and mark the position of the notches for ribs with a soft pencil. Remove the trailing edge and use a fine flat file to cut the notches according to the building plan. Lightly sand the CNC milled balsa ribs 1 (Det. G–G) to remove any imperfections.
