C13. Make a mark 4 - 7/8” from the leading edge centered on
the side of the wing core. In our model, the center point was 1 -
3/8” from the top and bottom. Drill a 1/4” hole on the mark and
test fit a dowel. Repeat on the other side.
C14. Make a mark 1” from the trailing edge centered on the
side of the wing core. In our model, the center point was 9/16”
from the top and bottom. Drill a 1/4” hole on the mark and test fit
a dowel. Repeat on the other side.
C15. Using the ply spoiler support, make an outline on the
trailing edge of the wing as indicated by the image above. The
edges on the spoiler support bracket should correspond to the
points on the wing where the mark will be made.
C16. Using a rotary tool set at 1/8” depth, cut away the foam
inside the lines created in step C15. Periodically test fit the spoil-
er support bracket into the cutout until you have established a
flush fit with the sides of the wing core.
The next steps outline covering the wing with our precut, self
adhesive vinyl covering. Be extremely careful when using a heat
applied covering. High heat will distort the foam and perma-
nently ruin the wing shape. These steps are best performed with
some help. Apply a thin coat of Super 77 Spray Adhesive before
covering any foam parts.
C17. Cut a strip of vinyl to 27” long. Staring on the bottom of
the wing, scribe a mark near the leading and trailing edge 11 3/4”
from one side of the wing. Carefully lay the first piece of covering
along the two marks centered on the wing. Squeeze out any air
bubbles starting in the middle and work your way out towards the
edges. Overlap the trailing edge, but do go onto the top of the
wing. Cut off any excess at the trailing edge. For the leading edge,
only overlap to the very tip of the leading edge. Cut off any excess
beyond the tip of the leading edge. The sides of the wing should
have about 1/8” to 1/4” overhand on the sides. You may need to
cut slits into the vinyl to follow the contour of the wing.
Repeat for the other half of the wing bottom. The two pieces of
vinyl covering should leave an overlap in the middle approxi-
mately 1/4”.
C18. On the wings top, scribe a mark 11 3/4” from the side of
the wing on both the leading and trailing edge. Using another
piece of vinyl cut at 27” lay the covering along the marks on top of
the wing. Squeeze out any air bubbles starting in the middle and
work your way out towards the edges. Cut away any excess vinyl
over the wing center cutout leaving approximately 1/8” to 1/4”
overlay. Fold over the excess into the center cutout area. Wrap the
covering 1/2 through the back of the trailing edge and cut off any
excess. Wrap the covering beyond the leading edge to the bottom
of the wing approximately 2” and cut off any excess.
Repeat for the other half of the wing top. The two pieces of vinyl
covering should leave an overlap in the middle approximately
1/4”.
