Building the Fuselage

5. Build the fuselage side frames over the plan using the laser cut parts F-1 and F-2. The remaining pieces of the side frames
are made from 3/32" sq. balsa strip.
6. Glue two 3/32" sq. strips across the front face of F-6 in the locations shown on the plan.
7. Pin the right fuselage side frame to the plan. Glue F-6 into position using a small square to hold it 90 degrees to the side
frame.
8. Glue F-3 into position using a small square to hold it 90 degrees to the side frame.
9. Glue the left side frame into position taking care to maintain a square and true assembly.
10. Glue F-4 into position.
11. Laminate F-5, F-BA and F-9 together and then glue this assembly into position on the fuselage.
12. Glue the 3/32" sq. stringers into position between F-3 and F-4. Glue the three 3/32" sq. cross pieces into position in the
cabin area.
13. Glue the 3/32" sq. stringers into position between F-3 and F-9.
NOTE: Make sure that these strips stop flush with the rear face of F-9 and do not block the slot between F-5 and F-9.
14. Pull the tail posts together and glue. Be careful to maintain a straight assembly and that the joined tail post is vertical and
not leaning to the left or right.
15. Working from the front to the rear, glue the 3/32" sq. cross pieces into position onto the fuselage between the cabin and the
tail.
16. Glue F-7 into position at the bottom rear of the fuselage.
17. Glue the two F-2A's into position.
18. Glue the 3/32" sq. stringers into position on the sides of the fuselage between F-6 and the tailpost.
19. Glue F-14 into position. Glue the 3/32" sq. filler strip to the top of the first crosspiece behind F-14.
20. Laminate parts F-10, F-10A, F-11, F-12 and F-13 together as shown on the plan.
21. Position the removable nose block on the front of the fuselage and sand to shape. Now sand the fuselage smooth all over.
22. Drill the 1/4" hole in the nose block for the propeller bearing. Be sure to put 5' down thrust and 3' right thrust in as you drill
this hole. Now set the fuselage aside until it is time to cover the model.

Building the Wing

Center Section:

23. Pin the 3/32" x 1/4" trailing edge to the plan. Pin the 3/32" sq. lower spar on the plan.
24. Glue ribs W-1 and two W-2's into position.
25. Glue W-3 and the 3/32" sq. top spar into position. Remove the center section from the plan when the glue is dry.
Outer Wing Panels:
26. Pin the 3/32" x 1/4" leading edge and trailing edge to the right wing plan.
27. Glue rib W-4 and four W-5's into position.
