Wing Construction
We begin construction with the
wing. Before starting construction, it is
a good idea to place wax paper on the
building surface to prevent gluing the
wing to the building board.
Locate the two wing halves
and the ¼” dihedral brace taped to one
wing
panel.
Trial fit the dihedral brace in
one of the wing halves.
Now slide the other wing panel
onto the dihedral brace until it meets
the other wing root. Check for
alignment. If necessary, slightly sand
the corners of the dihedral brace for
proper fit.
When you are satisfied with the
fit, remove the wing panels from the
dihedral brace. Mix about one ounce
of 30-minute epoxy and coat the
inside of the slot in each wing panel,
the dihedral brace, and the root rib of
each wing.
Now slide the dihedral brace
into one wing panel. Wipe away any
excess epoxy that may have oozed
out from inside the slot. Slide the
other wing panel onto the brace,
wiping away any excess epoxy with
a paper towel wet with alcohol. Tape
in place with masking tape until the
epoxy has cured.
When the epoxy has cured,
remove the masking tape and set the
