Section 2: Joining the Wing Halves
5. Allow the epoxy to cure completely before removing the
clamps.
6. Using a pencil and a ruler, mark the center or "V" section of the
wing joiner, or wing dihedral brace, you have just created. This
mark will serve as the center line when joining the wing halves.
7. Trial fit the dihedral brace, or wing joiner, into one of the
wing panels. It should insert smoothly up to the center line
marked in Step 6. Now slide the other wing half onto the
dihedral brace until the wing panels meet. If the fit is overly tight,
it may be necessary to lightly sand the dihedral brace. Check to
see if the alignment of the wing is accurate.
8. Now check for the correct dihedral angle. To do so, place the
wing on a large, flat surface (with the aileron rods hanging off
the edge) with one wing panel resting on the surface; the
opposite wing tip should be exactly 4
illustration below). A good point to measure from is where the
plastic wing tip joins the end of the wing panel. If the angle
'' from the surface (see

measurement is not 4 ⁄

one of the wing panels. Refit the wings and re-check the angle.
9. Separate the wing halves and remove the dihedral brace.
10. Place the wing halves on the flat surface so the bottoms are
facing upward. Note the wing root (the exposed wood end of the
wing halves) as shown below. Using a felt tipped pen, place a
mark at the leading edge and trailing edge of the servo bay
location on each wing half. These marks serve as a guide when
the slot for the aileron servo and aileron servo tray is cut out.
Note: Be careful to exactly mark this location as you do not want
to cut into the plywood surrounding this area later in Section 3.
11. Mix up approximately three ounces of 30-minute epoxy.
Note: When joining the wing halves, it is extremely important to
use plenty of epoxy.
12. Use a mixing stick or a scrap piece of wood to apply a
generous amount of epoxy into the wing joiner cavity of one wing
half. Make sure the epoxy is applied to all sides of the cavity.
