You can skin the wing in one piece or in two pieces. The method shown below provides detail on how to do it in one piece.

Begin by laying out the individual sheets as needed. Tape them together on the back side with masking tape.

Tack the carbon fiber pieces to the balsa sheeting using 3M77.

Cut a piece of 3/4 ounce fiber glass cloth large enough to cover the entire skin. Tack the cloth on using 3M77.

Cut a piece of 2 ounce glass approximately 5" wide and tack in place where the top and bottom skins join. This later becomes part of the ailerons.
