Building the Bottom Wing
44.
The bottom wing is built in two pieces and then joined with the proper dihedral angle. Cover the wing plans with wax paper.
45.
Glue the wing tip parts L-2 and L-3 together over the plan. When the glue is dry, set them aside.
46.
Build the right wing first by pinning the 3/32" sq. lower spar and the 3/32" x 1/4" trailing edge into position over the plan.
47.
Glue the inboard rib L-1 into position, using the dihedral gauge to establish the proper angle. The top of this rib should lean
toward the wing tip.
48.
Glue the remaining six L-1 ribs into position.
49.
Glue the 1/8" sq. leading edge into position.
50.
Glue the wing tip assembly into position.
NOTE: Be sure to raise the outer edge of the wing tips 1/8" while gluing them into position.
51.
Glue the L-4 rib into position. Glue the 3/32" sq. top spar into position. Bevel the ends to match the wing tips as shown on
the plan. Glue the 1/16" sq. strips into the notches into the wing ribs. The forward strip ends against rib L-4 and the rear
strip is beveled to match the wing tip like the top spar.
52.
Remove the wing from the plan and sand all of the outside edges round, taper the trailing edge and sand the assembly
smooth all over.
53.
Build the left bottom wing panel as you did the right hand panel.
54.
Glue the two bottom wing panels together. There should be 5/8" of dihedral under rib L-4 on each side.
55.
Test fit the bottom wing to the fuselage.
Building the Wheel Pants
56.
Start assembling one wheel pant by laminating four W-2's together.
57.
Laminate two W-1's and then glue them to one side of the W-2's. Now glue two W-1's to the opposite side to complete the
assembly.
58.
Build the second wheel pant in the same manner as you did the first.
59.
Sand the wheel pants to shape.
Covering the Model
60.
Sand the entire structure smooth with 320 grit sand paper.
61.
Cover the interplane struts and then glue them into position on the fuselage.
62.
Cover the rest of the fuselage except the bottom between F-2A and F-4 , the wings, the wheel pants and the tail surfaces
with tissue using clear dope,
63.
When the dope is dry, shrink the tissue by lightly misting it with water.
64.
Apply two coats of clear dope thinned 50-50 to the entire model.
65.
Apply the decal's to the model in the positions shown in the illustration. Paint the inside of the cockpit and the front of F-4
black.
