Center the yardstick on the spar, and press it in place.
Then, push a ziptie through the foam, at each edge of the yardstick, and
zip tie the yardstick to the foam.
Here's what it
looks like from the back side:
Now if your wing
has dried, you are ready to install the spar.
First put a dummy
spar into the wing, slide it in, and flip it up. Scoot it behind the real
spar location. I use my straightedge for this task
Wet the sides
of the foam that polyglue to the coro with a water mist, and wipe off the
excess. Then apply a generous bead of polyglue to the spar, both top and
bottom.
Slide the spar in, and flip it up into position. Make sure
you get it between the spar lines. Place it aside and let the polyglue
dry. The wing is finished.
Here's an end pic of the wing,
with the spar installed, and the glue cured.
You can't see
it in the picture, but thats the wing and fuselage on the scale, before the tail
feathers. The weight before tail feathers is 1 lb 15.5 oz. after tail
feathers is 2 lb, 4 oz.
