Now that the bottom fuselage piece is glued into place, you can locate the
carbon fiber rods used for the wing bracing. Shown above is the wing joiner
used to guide the wing bracing. You will also find dots towards the tip of each

location on the bottom part of the fuselage. There should be four total carbon
rods for wing bracing (313mm each). Two will be used on each wing.
