8. Pin a Spar assembly to the building
board at three or four locations using the cross-
pinning technique shown in the sketch with the
Doublers up.
9. Glue the die-cut 3/32" balsa ribs W-2
through W-12 to the Spar. These should be
vertical and aligned over their appropriate
locations as indicated on the plans. The jig tabs
located near the aft end of the ribs should all
contact the work surface.
10. Glue the aileron Trailing Edge
assembly to the aft edge of ribs W-8 through
W-12. The upward facing edges of the ribs and
the Trailing Edges should be even and the jig
tabs should all be touching the work surface
during this step.
NOTE: The inboard end of the aileron
TE extends approximately 15/16"
inboard of rib W-8, as shown on the
plan.
11. Glue the lower 1/8" x 3/16" x 21" balsa
TE Spar as far forward as possible in the slots in
ribs W-2 through W-8.
12. Glue the lower 1/8" x 1/8" x 21" balsa
Flap LE into the aft portion of the slots in ribs
W-2 to W-7. There should be a 1/16" gap
between the TE spar and the flap LE.
13. Repeat steps 11 and 12 for the slot in
the upper side of the ribs.
14. Glue the 1/2" x 21" tapered balsa
