15. Remove the wing from your building board and
carefully sand off any glue blobs. From the remaining 1/32"
x 3" x 15" [.8 x 75 x 380mm] balsa sheet, cut pieces to make
bottom center sheeting to fit between the leading edge
dowel and wing spar and from the wing spar to the trailing
edge sheet.
❏ ❏
16. Cut and sand the wing spars and trailing edge
sheeting flush with the wing tip rib.
❏
17. Return to step 2 and build the right wing panel.
Remember! Build it over the right wing plan.
❏
1. Draw a centerline on the laser-cut 1/16" [1.6mm] ply
dihedral brace.
❏
2. Using a hobby knife, carefully cut a 1/16" [1.6mm] slot
in ribs W-1A, just behind the main spar. Test fit the dihedral
brace in the slots.
❏
3. Test fit the wing halves together. With one wing half flat
on your building board, block-up the wing tip of the other
wing half so that it is 4-1/2" [114mm] off of your building
board. Use a bar sander to sand the center joint as
necessary until the wing halves fit together without any gap.
❏
4. When satisfied with the fit, apply medium CA to the
face of half of the dihedral brace. Insert the dihedral brace
into one of the wing halves so that the brace is attached to
the two main spars. After the CA has cured, apply medium
CA to the face of the other half of the dihedral brace and the
root rib. With one wing half flat on your building board and
the wing tip of the other wing half blocked up as before,
quickly slide the two wing halves together. Before the CA
hardens, make sure the trailing edges are aligned. Note: If
you prefer more working time for joining the wings, use
epoxy for this step.
❏
5. Sand the leading and trailing edges of the wing joint flush.
❏
6. Use the wing tip template on the wing plan to make
two wing tips from the unused portion of 1/16" [1.6mm]
balsa that the fuselage sides came from.
