3. Thin the outer 4” of the balsa spar to allow the fit of
the last two ribs. Thin to 1/8”.
4. Slide W5, W6, W7, and W8 onto the Ply Spar, align,
and glue.
5. Glue W17 to the trailing edges of the ribs.
6. Drill a hole in W20 and assemble the bellcrank to it.
7. Slide W20 into the slot in W8 (the bellcrank will be on
the bottom of W20) and cut the pushrod housing and
pushrod to size. Attach a clevis to the pushrod and
the bellcrank and align the assembly.
8. Slide W9 in place, slide W20 into the slot in W9, and
glue all the pieces.
9. Glue W10, W11, and W12 in place.
10. Glue W18 against W17 and to the trailing edges of
W9 thru W12. Glue the remaining ¼ x ¼ x 24 balsa
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).
12. Select two 1/16” x 4” x 24” sheets. Cut a 1/16 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.
14. Mark a point 9/16” perpendicular to W17 at W8.
Mark another point 11/16” perpendicular to W18 at
W12. Connect these points and the trailing edge of
the center section. Trim the top sheeting to match
these lines.
15. Remove the tabs on the rib bottoms, and bevel the
top sheeting trailing edge to match the bottom rib
camber.
16. Mark the location of the exit point of the aileron link-
age so the slot can be cut after sheeting.
17. Select two 1/16” x 4” x 24” balsa sheets. Edge glue
these two pieces and the remaining 3 x 18 sheet to
form the bottom sheeting.
18. Trim the sheeting to fit the leading edge, and sand
the inner edge to match the center section sheet-
ing. Sheet the bottom of the wing panel.
