28. Glue the wing tip pieces W-7 and W-8 together over the plan.
29. Raise the end of the wing tip 3/32" from the building board and glue it to the leading and trailing edges.
30. Glue rib W-6 into position.
31. Glue the 1/16" sq. and 3/32" sq. top spars into position. The inboard ends should be long enough to extend past W-2
slightly. The outboard ends should be beveled to fit the angle of the wing tip. When the glue is dry, remove this wing panel
from the plan.
32. Now build the left wing panel in the same manner as you did the right.
Joining the Wings:
33. Pin the wing center section over the plan.
34. Lay the left wing in position. Raise the tip so that there is 1 1/4" dihedral under rib W-6 and pin into position. Securely glue
the wing panel to the center section.
35. Join the right wing panel to the center section as you did the left.
36. When the glue is dry, remove the wing from the plan. Sand the leading edge and the tips round and taper the trailing edge.
Sand the wing smooth all over and then set it aside until it is time to cover the model.
Floats or Wheels?
37. You must now decide if you want to build the floatplane version or the landplane version. To build the land plane version,
skip ahead to step #48. To build the floatplane, build the floats now as described starting with the next step.
Building the Floats:
38. Build the first of four float side frames over the plan using 3/32" sq. balsa strips. Soak the bottom front strip in hot water for
15 minutes, wipe it dry and then pin it to the plan. Allow the side frame to dry completely before removing it from the plan.
39. Build the remaining three float side frames over the plan as you did the first.
40. Pin the float formers A, B, C, D, E, F and G upside down on the top view of the float on the plan. Glue the side frames to the
formers. Make sure that the float remains straight and that the top of each side frame is flat on the building board.
41. Glue the 3/32" sq. rear keel into position. Soak the forward keel in hot water for 15 minutes before gluing into position.
42. Glue two short strips of 3/32" sq. balsa to the rear face of former D between the side frame and the lower rear keel.
43. When the float is dry, remove it from the plan and glue the nose block into position.
44. Sand the float smooth and shape the nose block. Now build the other float as you did the first.
45. Build the two float struts over the plan using 1/16" x 3/16" spruce strips. When the glue is dry, remove it from the plan and
sand the edges round.
46. Cut the two 5 3/4" long float spreaders to length and sand them smooth and round the edges.
47. Glue F-8B into the slot between F-5 and F-9 and sand flush with the bottom of the fuselage. Sand part H smooth and round
the edges. Now set the float parts aside until covering the model. Now skip ahead to step #51.
Building the Wheel Landing Gear:
48. Bend the landing gear wire to shape using the pattern on the plan.
49. Test fit the landing gear wire into the slot between F-5 and F-9. Do not glue the wire into position until after the model is
covered.
