spar in place. Thin the outer 4” to 1/8” to fit in W11
and W12.
11. Cut the 3/8 x 1 x 36 balsa leading edge to length,
and glue in place. Cut scrap 1/16” balsa for shear
webs and glue in place (see plans for location).

x 3 x 36 balsa sheet in half. Edge glue the two 4”
sheets and one 3” sheet to form the top sheeting.
13. Trim the leading edge to fit, and sand the inner
edge to match the center section sheeting. Sheet
the top surface of the right wing panel.

Glue one of these spars to the Ply spar, aligning it
