Building Instructions JIMMY
Glue the ply dihedral brace to the rear
of the spars and to the bottom
planking. The dihedral brace dictates
the way the two wing halves fit
together, so ensure that the underside
is parallel to the building board. The
kink in the brace should exactly match
the position of the slanted front rib
part. If necessary, sand a little off the
end of the brace to achieve this. Be
sure to clamp the brace to the spars
until the glue has set.
Glue the 8x8 mm leading edge in
the cut-outs of the ribs, and
temporarily fix it with pins as shown
in the picture.
Glue the rear parts of the 3 mm balsa
root ribs onto the bottom planking and
against the dihedral brace. The first rib
is again angled at the same angle as
the front part (check with the template),
and at right angles to the spars.
