Remove the major parts of the kit from the box (wings,
fuselage, tail parts, etc.) and inspect them for damage. If any
parts are damaged or missing, contact Product Support at
the address or telephone number listed in this manual.

1. Where necessary, use a covering iron with a covering

sock to tighten the covering that may have loosened during
storage. Apply pressure over sheeted areas to thoroughly
bond the covering to the wood.

2. Using a sharp hobby knife, cut the covering away in the

following areas on the top of the wing: wire outlets (4), L.E.
dowel hole (1), wing bolt holes (2).

3. Using a sharp hobby knife, cut the covering away in the

following areas on the bottom of the wing: wire outlets (2),
gear openings (2), wing bolt holes (2), servo openings (2)
(on left and right panels, not pictured).

4. There are two strings inside the wing center section

that have the ends taped to each root rib. Move the forward
string from the root rib and put it through the hole in the
bottom of the wing. Tape it to the wing as shown.

5. Use 6-minute epoxy to glue the four 3mm plywood

wing joiners together, making two pairs as shown in the
photo above. Use weights or clamps to hold the joiners in
place until the epoxy cures. Important: The joiners may be
marked with arrows to indicate which way is up and which
end points towards the tip. Be sure to orient the pieces as
shown in the photo. If your joiners are not marked with
arrows, mark them with a pencil. The wing tip end is narrower
(21mm) than the root end (23mm).
