16. Trim and glue 1/16" x 1/4" x 30" [1.6mm x 6.4mm
x 762mm] balsa cap strips to the top of ribs W6 through W10.
❏ ❏
1. Remove the outer wing panel from your building
board. Sand any excess glue from the bottom. Also, sand
the sub LE flush with the bottom of the wing ribs.
❏ ❏
2. With the wing upside-down, pin the top wing spar,
at rib W4, flat against your building board. Position the 1/4"
x 5/8" x 30" balsa wing leading edge under the TE. Do not
glue it to the TE. Place a leftover 1/4" x 1/2" [6.4mm x
12.7mm] stick under rib W10 so that the rib is1/4" [6.4mm]
off of the building board. Use T-pins or weight to hold the
wing in position.
❏ ❏
3. From one of the 1/16" x 3" x 30" [1.6mm x 76.2mm
x 762mm] balsa sheets, cut two strips, one 3/4" [19mm]
wide and a second one 1-1/2" [38.1mm] wide. Glue the 3/4"
[19mm] wide strip to the edge of a second 1/16" x 3" x 30"
[1.6mm x 76.2mm x 762mm] sheet to make a lower forward
wing sheet.
❏ ❏
4. To glue the lower forward wing sheet to the bottom
of the wing, apply a bead of medium CA to the forward half
of the bottom main spar. Position the wing sheet so that the
aft edge of the sheet is centered on the bottom main spar.
When the CA has cured, apply a bead of medium CA to the
bottom of each wing rib and along the sub LE. Pull the sheet
down, making sure it contacts the surface of each rib and
the sub LE. Hold it in place until the CA has cured.
❏ ❏
5. Trim the 1/16" x 1-1/2" x 30" [1.6mm x 38mm x
762mm] balsa strip, cut in step 3, to fit along the aft edge of
the ribs, from rib W5 to W10, flush with the aft edge of the
TE. Trim a second TE strip to fit from W4 to W5. When
satisfied with the fit, glue them to the bottom of the ribs and
the 1/4" [6.4mm] TE.
❏ ❏
6. From the remaining 1/16" [1.6mm] balsa sheet
used in step 15, sheet the outer wing panel from rib W4 to
W5.
❏ ❏
7.Trim and glue 1/16" x 1/4" x 30" [1.6mm x 6.4mm x 762mm]
balsa cap strips to the bottom of ribs W6 through W10.
❏ ❏
8. Remove the outer wing panel from your building
board. Trim the forward wing sheeting flush with the sub LE.
❏ ❏
9. Glue the 1/4" x 5/8" x 30" [6.4mm x 15.9mm x 762mm]
balsa leading edge to the front of the sub LE.
❏ ❏
10.Trim and sand the LE, sub LE, top and bottom sheeting,
wing spars and TE flush with rib W4. Trim the sub LE, top
and bottom sheeting and wing spars with rib W10. Leave
the excess LE and TE until after the wing tip is installed.
❏ ❏
11. Use a Great Planes Power Plane and sanding bar
to shape the LE to the shape shown on the wing plan.
❏ ❏
12. Use a razor plane and sanding bar to shape the
TE to the shape shown on the wing plan.
