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 sheeting.
Sheet the bottom of the wing panel.
19. Trim the trailing edge to match the top sheeting
and the center section sheeting.
20. Glue on the wingtip. Sand to shape.
Note: the slots in the trailing edge in the picture will be
cut later.
The remainder of wing construction will be accom-
plished after fuselage assembly.
Fuselage Assembly
1. Pin two ¼ x ¼ x 36 balsa spars to the fuselage top
view as shown. Cut a ¼ x ¼ balsa stock for a fin post.
Glue in place. Bevel the ends of the spars to fit at the
fin post.
2. Bevel the top edge of F2A to match the angle of
F1A. Glue F2A in place.
3. Using the fuselage angle gauge provided, set F1A
in place and set the angle. F1A will rest against F2A.
Glue in place.
4. Glue the bulkheads F3A through F10 in place.
5. Add ¼ x ¼ balsa keels between F1A and F3A, and
between F5A and F8A.
6. Glue F12 in the slots in F8A and F9A.
7. Align F11 with F9A and the fin post, resting on F10.
The top edge of F11 will align with the bottom of the
notch in F9A. Glue in place.
8. Add 1/8 x ¼ balsa stringers to the fuselage, starting
with the bottom row first. Add the stringers simulta-
neously to each side; this will help keep the fuse
straight. Bevel the stringers that attach to the fin
post.
9. After the bottom row is in, add F21 and F22 Cockpit
Floors. Note that F22 buts against F5A.
10. Continue adding stringers, noting that the third row
stops at F10. This row will also twist as you lay it in
the grooves. Also note that this row does not extend
between F3A and F5A.
