4. Pick out the root end of each wing panel to be joined and layout, on the foam,
the notch in the leading edge. Also layout the the slot for the 3/16" ply wing
joiner
W1
. Note that the slot is cut back along the spars allowing
W1
to tie in with
them. The dimensions are specified on the plans.
5. Cutting the notch and slot can best be done on a scroll or band saw. A hand
coping saw can be used if you are careful.
Tip:
Mount the wing core in its
shell and tape in place. This will hold it in a level position when cutting the
notch and slot allowing for a better fit against F2 in the fuselage.
6. Butt the wing panels together and trial fit
W1
wing joiner. Check to see that
the trailing edge lines up. This may reguire some sanding. A two foot long
sanding stick with 100 grit paper is ideal for truing edges. Don't even think about
gluing the panels together yet.
7. Install a 5/16" sq. x 30" balsa stick on the trailing edge of each core. Use
white glue and hold it in place with masking tape. Make sure it is centrally
located. When cured block sand to conform with the airfoil.
Note: it is
important to shape the trailing edge down so when the rear sheeting is
installed and sanded the total thickness at the trailing edge is 5/16"; the
same thickness as the aileron.
8.
Lay a 3/32" x 2" x 30" balsa sheet flush with the trailing edge. Use the
opposite edge to draw a line from end to end. Apply contact cement in this area.
Also apply contact cement on one side of the 3/32" sheet. We recommend Sta'-
Put II Spray Adhesive especially formulated for Styrofoam. It is also water
resistant.
When installing the sheet becareful to rest it on a flat surface!
Use this method to sheet all four trailing edge pieces.
9. Measure in 1/8" from the front edge of the wing spar. Strike a line the full
length of the wing panel on all four spars.
10. Apply contact cement in the area between the line on the spar and the
leading edge. Apply contact cement to one side of four 3/32" x 3" x 30" sheets.
When ready install each sheet by placing the edge on the line located on the
spar.
Make sure you work on a flat surface while pressing the sheets in
place.

.
Trim off the excess sheet on the leading edge flush with the foam.
A long
sanding stick will come in handy here. Glue the 3/8" x 7/8" x 30" leading edges
in place. If the stick is crowned do not try to straighten it when taping in place.
We have allowed extra width allowance on the leading edge. Use white glue and
hold it in place with masking tape until cured.
