edge and the rear window opening. Glue the doublers in place
making a RIGHT and a LEFT cabin side! D 11. Securely glue the die-cut 1/8" ply F-2D to the
tapered balsa filler and to the cabin sides.
D 8. Trial fit the die-cut 1/8" ply cabin sides into the
notches in the fuse sides, sanding as necessary for a good fit.
Glue the cabin sides to the top edge of the fuse sides and to
F-5T.
D 9. Glue the cabin sides to F-4T while pushing F-4T
against the aft ends of the wing saddle doublers; and glue the
cabin sides to F-2T while pushing F-2T against the front ends
of the wing saddle doublers.
D 10. Trial fit the 4-3/16" length of tapered balsa at the top
rear edge of F-2T, between the cabin sides, and glue in place.
D 12. Find the 1/4" ply wing hold-down plate and trial fit
it into the notches in the fuse side doublers, sanding as
necessary for a good fit. Glue the hold-down plate in place
securely, using 30-minute epoxy, then build up small fillets
of epoxy all around the plate to lock it in place.
D 13. Securely glue the two die-cut 1/8" balsa stab sup-
ports and the tapered balsa tail post to the aft end of the
fuselage. IMPORTANT: Before gluing these parts, tape
and pin them in place and check alignment as follows: The
tail post must be installed perpendicular to the top edge of the
fuselage, and must be vertical. Cut and sand off the top of the
tail post flush with the top of the stab supports, and sand the
aft end of the stab supports to blend with the fuselage. See
- sketch at the top of the next page.
