Wing Assembly

*Note* We highly recommend using 30 Minute
Epoxy over faster curing epoxies for several
reasons. First, slower curing epoxy is stronger. It
also providers more working time, allowing the
builder to properly align the parts. Using fast cure
epoxy when joining the wing halves could result in
the glue drying before the wing halves are aligned
properly, causing damage to the wing assembly.
Also, when joining the wing halves, the entire area
of both center ribs need to be joined completely
with no gaps existing. Not following these steps
carefully, may result in failure of the wing center
section during flight.
1) Locate the wing dihedral brace. Using a ruler,
locate it's center and place a mark. Draw
vertical line at the mark just made .
Center line
2) Test fit the dihedral brace into each wing half.
The brace should slide in easily up to the
centerline you drew. If it does not, use 220 grit
sandpaper with a sanding block and sand down
the edges and ends of the brace until the proper
fit is obtained.
3) When satisfied with the fit of the dihedral
brace in each wing half, remove the brace .Mix
equal amounts of part A and part B 30 minute
epoxy. Coat all sides of the dihedral brace box
and half of the wing brace with the epoxy. Make
sure to cover the top and bottom as well as the
sides. Use enough epoxy to fill any gaps.
4) Insert the dihedral brace into one wing half up
to the centerline. Wipe off any excess epoxy that
may have squeezed out of the joint using paper
towels.
Remover the covering
5) Once the epoxy has cured, trial fit both wing
halves together.The center gribs should fit flush
together with little or no gaps existing. If gaps do
exist, use 220 Grit sandpaper and sand down
the high spots on the root ribs and the wing
joiner until the proper fit is obtainer.
6) To protect the covering from the epoxy used
to glue the wing halves together, carefully apply
masking tape around the edge of the root rip on
the top and bottom of each wing half.

7) Mix a generous amount of 30 minute epoxy.
Coat the exposed half of the dihedral brace, the
wing joiner box and both root ribs with epoxy.
Slide the two wing halves together and carefully
11
align them at the leading and trailing edges.
Wipe away any excess epoxy using paper
towels. Use masking tape wrapped around the
center section to hold the halves in place until
the epoxy cures.
8) When the epoxy has cured, carefully remove
the masking tape from the wing.
9) Peel off the backing from the self adhesive
covering strip used to cover the center section
wing joint seam. Apply the strip to the center
section of the wing on the bottom first, and the
top using the rest of the material.
