1. Locate the items for this section of the manual.
2. Fold the covering back and use tape to secure it to
the wing. Slide the carbon tube into the wing panel. The tube
socket has a cap on it, so do not force the tube in any farther
than it will easily slide.

3. Slide the wing into position on the fuselage. Don't
slide the wing tight against the fuselage at this time. Use
plastic to prevent gluing the wing to the fuselage. Fit the
wing root extension to the wing. Check the fit of the wing
root extension by sliding the wing and extension tight
against the fuselage. The outside edge will align between the
wing and extension as shown.
4. Slide the wing away from the fuselage and remove
the extension. Mix 1/2 ounce (15mL) of 30-minute epoxy.
Use an epoxy brush to apply a thin coat of epoxy to the
adjoining surfaces of the wing and the extension. Reposition
the extension and slide the wing tightly against the fuselage.
Use a paper towel and denatured alcohol to remove any
excess epoxy. Use low-tack tape to hold the extension in
position until the epoxy fully cures.
5. Once the epoxy has cured, remove the wing panel
from the fuselage. Remove the tape, then use a covering iron
to seal the covering from the wing to the wing root extension.
6. Repeat steps 2 through 5 to prepare the opposite wing
panel. Remember to remove the plastic from the fuselage
once both wings are complete.
