D 6. Position the TE on the aft end of the ribs, flush with
the top and bottom edge of the ribs. Use a straightedge to
check that the TE is straight before gluing it in position.
Trim the root end to match the plan.
D 7. Fit the second TE, trimming the root end to butt
against the first TE. Use a straightedge to check that the
TE is straight before gluing it in position.
D 8. Glue ribs R-1 to the bottom main spar, perpendicular
to the building board.
D 11. Glue the die-cut 3/32" balsa ribs R-4 flush with both
sides of R-5.
D 9. Use 30-minute epoxy to glue the 1/8" plywood joiner
between the R-1 root ribs, perpendicular to the building
board. The center of the joiner should be flush to the aft
edge of the main spar and the joiner ends should be flush
with the forward edge of the main spar. Make sure the top
of the joiner is flush with the bottom of the slots for the top
main spar.
D 12. Use 6-minute epoxy to glue rib R-6 to the joiner
and the TE. Make sure that the rib is seated on and
perpendicular to the building board. Glue rib R-5 to the front
of the joiner and spars, perpendicular to the building board
and parallel with the R-1 root ribs.
D 13. Trim the leftover LE to fit between ribs R-1 and R-5,
centered on the front of ribs R-4. When satisfied with the fit,
glue them in place.
D 10. Use 30-minute epoxy to glue the top spar to the
joiner and thin CA to glue the joiner to the ribs. Hold the
spar in place with a weight until the epoxy cures.
U 14. Use 6-minute epoxy to glue the die-cut 1/8" plywood
leading edge joiner (LEJ), centered vertically, across the
joint between the center LE and the outer LE.
