6)
Installing Carbon-Fiber Spars
: Locate two rectangular carbon-fiber spars (F). A spar will be glued into
each 1mm wide channel provided on bottom surface of each wing panel.
7)
Using back end of a ball point pen or pencil, firmly press carbon spar into provided channel so that it is
slightly recessed. Make sure end of the spar does not protrude from end of wing which faces fuselage.
See Figure 3.
8)
Hold wing so that one end of spar is higher than the other (this allows the glue to better flow along the
channel). Starting at highest point, drip thin instant glue (i.e. “CA” or cyanoacrylate) into spar channel
every 2-3 cm, working your way along entire length of channel. Notice that glue wicks naturally into
channel and around carbon spar. If you notice that glue drop only wicks along one side of spar, make
sure to add some glue to other side. CAUTION: If excessive glue is applied it WILL run out open end of
channel and may drip onto whatever is below it.
9)
Complete steps 6-8 for remaining wing panel.
10)
Locate two 45mm (1.75 in) black plastic wing joiner tubes (H). If you would like to assemble wings as
one piece for minimum weight and complexity, proceed to Step 11.
If, however, you would like to
utilize the optional three-piece wing add-on kit you purchased separately for easy travel and
storage, refer to page 21.
11)
As shown in Figure 4,
firmly
press each black plastic wing joiner tube (H) into provided channel located
at end of each wing panel. Disregard extra ring of space provide around center of tube, as this is
provided for the three piece wing add-on option. Do not attempt to fill this space surrounding tube
with glue or filler.
12)
Apply thin instant glue to exposed sides of tube, allowing it to wick down and in between foam and
plastic tube. Do not apply excess glue around ends of the tube. See Figure 4 on the following page.
Using back end of a ball point pen or pencil, firmly press tube down to ensure a good, tight bond
between foam and tube.
