3. Test fi t the wing panels into the wing pockets in the
fuselage. The wing spars that extend beyond the root rib are
designed to interlock with each other when the wings are fi t in
place. Confi rm that the wing root ribs fully seat into the pockets.
If not, sand the ends of the spars as necessary until they do.
The fuselage stand is designed to fi t into the fuselage hatch
cutout and support the fuse just behind the fi rewall as shown.

4. Before you begin this step, prepare a weighted object to
hold the fuselage and wings in place while the epoxy cures.
We used a sock fi lled with sand as shown in the picture. Coat
the root ribs of the bottom wing panels with 30-minute epoxy
(Do not put epoxy on the spars until instructed to do so in the
next step). Put a coating of epoxy in the wing pockets as well.
Insert the wing panels into the fuselage and place the plane
onto the fuselage stand. Place your weight onto the top of the
fuselage to hold it down. Slide the wing supports underneath
the second outer wing ribs. The front edge of the supports
should line up with the LE of the wing panels. Confi rm that
the wing panels are fully seated in the pockets and the wing
is sitting fl at on the supports. Wipe away any excess epoxy
with denatured alcohol and let the epoxy cure undisturbed.

5. Apply a coat of epoxy to the
plywood spar doubler
on the side with the thin balsa laminate. Coat the aft side of
the wing spars with epoxy. Use small clamps to hold the spar
doubler to the aft side of the spars while the epoxy cures.
