6. Inspect balsa wood spars for knots and install spars
with knots to the outside edge of the wing. Install
3/16” x 3/16” balsa wood spars so that the two
pieces meet in the center of the wing (top and
bottom). Again, it’s important not to glue until
told to do so! (Fig. 6)

7. Bevel both sides of the trailing edge crutch before
installing. Do not cut tabs until after the trailing edge
is beveled. This will keep the part from breaking
during beveling process (Fig. 7). Use the provided
jig to gauge bevel.
