Glue F37 to the F36's inline with the angle and flush with the
front as shown.
Glue F39 to the opposite end of the F36's about 3/8" down
from F38.
Glue the two F40's together as shown and align with the F34
pieces on the wing. Sand to shape as shown. You will need
to contour the piece with the wing dihedral.
Glue the F40 assembly to the ends of F36 as shown.
Set this piece aside until you finish covering the wing.
WING FILLETS:
Fill in the seams of the strip sheeting with balsa filler and
sand to a smooth rounded shape. Make cuts around the tail
gear steering arm so that it moves smoothly.
Bolt the wing to the fuselage and lay a piece of wax paper or
plastic wrap along the wing where it meets the fuselage. This
will eliminate the possibility of gluing the fuselage to the wing
when adding the fillet.
