44..Place ribs W2 through W-9 into position. Pin the aft ends to the building board and glue the ribs to the lower
spar. These ribs should all be 90 degrees to the building board.
45..Place the top spar into position. It should extend past each end of the wing about 1”. Glue the top spar to ribs
W-2 through W-9.
46..Place part SW-1 into position against W-2 and the main spars. The angled end should face where the W-1 rib
will go and it should positioned so that the top edge is flush with the top of the top spar. The angle should allow
the top of rib W-1 to lean slightly toward the wing tip. When properly positioned, glue SW-1 to the spars and rib
W-2. NOTE: The top inboard corner of the SW parts is marked with a small “X”.
47..Place rib W-1 into position. Pin the aft end to the plan and glue the rib to the spars and to SW-1.
48..Slide the lower 1/16” x 1” trailing edge sheet into the slots in the aft ends of the ribs and glue into position.
49..Glue the 3/16” sq. trailing edge to all of the ribs and to the lower trailing edge sheet.
50..Glue the top 1/16” x 1” trailing edge sheet into position on the tops of the ribs and the 3/16” trailing edge.
51..Glue parts SW-2, SW-3 and SW-4 into position on the back of the spars. The tops of these parts should be flush
with the top of the top spar.
52..Place the 1/4” sq. leading edge into position. Nick the leading edge with your knife and crack it to make the
bends at ribs W-2 and W-4. Now glue the leading edge to the ribs.
53..Fit the top leading edge sheet (marked “T”) into position and glue it to the 1/4” sq. leading edge. Wet the top of
this sheet slightly and press it down and glue it to the ribs and to the top spar.
54..Use the 1/16” x 3” sheet to sheet the center section of the wing from W-1 to slightly past W-3.
55..Remove the wing from the plan.
56..Drill the 3/32” hole in the inboard end of the landing gear block as shown on the plan and then glue this block
into position in ribs W-3 and W-4.
57..Install the lower leading edge sheet as you did the top sheet. This sheet should also be glued to the landing gear
block.
58..Use the 1/16” x 3” sheet to sheet the center section of the wing from W-1 to slightly past W-3.
59..Trim and sand the spars and sheet flush with ribs W-1 and W-9.
Sand the wing smooth and sand the leading edge round.
60..Use the tip of your knife to locate the slot in the landing gear block through the lower leading edge sheet and cut
the sheet away that covers the slot.
Building the Right Wing and Joining the Wings:
61..Build the right wing as you did the left wing.
62..Test fit the right and left wing panels together. With one wing panel on your building board you should have
approximately 4 1/2” to 4 3/4” dihedral as shown on the plan. Now glue the two wing panels together.
63..Slide the nylon tubes onto the two aileron torque rods and then bend and trim the outboard ends as shown on the
plan. A small drop of oil in the nylon tube will help prevent glue from sticking them to the torque rods later on.
64..Cut a small notch in the aileron torque rod blocks for the upright leg and test fit them to the wing. After
achieving the proper fit you can glue the torque rod blocks to the wing. Glue them carefully so as not to glue the
torque rods to the nylon tubes.
65..Use thin C/A glue to attach the 1” nylon tape to the joint between the wing panels. Glue one end at the top
trailing edge with a small amount of glue. Now stretch the tape around the wing tightly and glue the tape
completely into position. When the glue is dry you can trim away any excess and then lightly sand the tape
smooth.
66..Glue the wing tip blocks into position on the ends of the wing.
67..Mark the centerline on the front edge of the ailerons. Bevel the front of the ailerons to the shape shown on the
plan. Drill and notch the inboard end of the ailerons to hold the torque rod. Temporarily hinge the ailerons to the
wing and trim the outboard ends of the aileron to fit with a small gap between them and the wing tips.
68..Clamp the ailerons into alignment with the torque rod blocks with cloths pins and then trim and sand the wing
tips to shape. The back ends should match the bevel on the ailerons.
