BUILDING THE WING
NOTE: The wing is built directly on the plan, so cover the plan with wax paper
before assembly. These instructions are identical for both the right and left wing
panels.
27.
Start building the right wing by pinning the lower 1/4" sq. spruce spar to the plan.
Also, pin the 1/4" sq. balsa trailing edge to the plan. The inboard ends should be
located as shown in the photo. The outboard ends will extend past the last W-4 rib
at the wing tip.
28.
Place rib W-1 into position. It should be 90° to the building board. Glue W-1 to the
spar and trailing edge. Glue the W-4 rib against the outboard side of W-1.
29.
Place the two laser cut lite ply shear webs (W-2) into position. Use a scrap of 1/4" balsa from one of the laser cut sheets as
a spacer to maintain proper separation between the F-2’s. Glue the F-2’s to the main wing spar and to rib F-1.
IMPORTANT NOTE: One end of W-2 is 90° and the other end has a slight angle. The end with the angle should face
inboard. Use the front view on the plan to help identify the proper alignment.
30.
Place rib W-3 into position. Because of the angle on the inboard end of W-2, the W-3 will not be 90° to the building board
but instead it will lean slightly toward the wing tip. Glue the rib to the main spar and to the W-2 shear webs. Be sure to align
the shear webs with the top spar notch before gluing.
31.
Place parts W-5 and W-6 into position between W-1 and W-3. Note that there is an angle on one end of these parts which
should be oriented the same as the W-2 shear webs.
32.
Carefully cut the spar joiner slots in ribs W-1 and W-3 as shown. You can use your hobby knife or razor saw to make these
cuts.
33.
Position the remaining W-4 ribs on the spar and trailing edge and glue in place. These ribs should be 90° to the building
board.
34.
Place the top 1/4" sq. main spar into position with the inboard end flush with the face of the W-3 rib. Make sure the spar is
completely seated in the slots in the ribs and glue the spar in place. The inboard end should be flush with the top of the W-
2’s. Place the 3/32"x1" trailing edge sheet into position and glue it to the top of the 1/4" sq. trailing edge and the wing ribs.
35.
Glue the 3/32" balsa shear webs to the back of the main spars in the second and third rib bay as shown. These shear webs
have the grain oriented vertically. The parts provided in the kit are slightly long and should be trimmed to achieve a tight fit
against the wing ribs. The shear webs should be glued to the spars as well as the wing ribs.
