Q Q 13. Fit rib W3-T to the outer panel and

accurately align it over its location on the plan. Use
the wing tip dihedral gauge to set W3-T at the correct
angle, then glue it in position with medium CA.

Q Q 14. Make a gusset from the end of the

1 /4" x 1 /4" x 15" balsa stick. Glue it with medium

CA at the position shown on the plan.

Q Q 15. Remove the T-pins. Lift your wing from

your building board and peel off the wax paper.

Inspect the wing panel and add CA to glue joints

that don't look strong.

Q Q 16. Make a 3/32" x 3/4" shear web from
the same balsa sheet you used to make the other
shear webs (originally a 3/32" x 3" x 15" sheet).

Then fit but do not glue it between ribs W3-T
and W4.

Q Q 1 7. Use your bar sander and 150-grit
sandpaper to sand the ends of the spars, LE and TE's
so they are even with rib W3-T and W9.

Q Q 20. Cut the 3/4" x 12-1/4" balsa triangle
stock into two 6-1/8" pieces to make the wing tips.
Use medium CA to glue a tip to W9 so the aft edge

of the triangle wing tip aligns with the aft edge of
the TE.

U U 21. Roughly carve the wing tip with a razor
plane or a hobby knife, then final shape the tip and
blend it to W9 with a bar sander and 150-grit
sandpaper.

U U 22. Use a bar sander and 220-grit sandpaper
to carefully remove any glue blobs and blend all the
ribs/ spars/ TE and LE.

LI Q 18. Use a sharp #11 blade to remove the
portion of balsa between the lines you cut with a
straightedge on rib W3-T.

Q Q 19. Roughly shape the LE the same way you
did for the inner wing panels.

Q 23. Arrange the plan so the left outer wing panel
is on your building board. Cover it with wax paper.
Return to step 1 and build the left wing panel the
same way as the right. Don't forget to switch to the
left wing panel plan so you do not build two right
panels.
