piece of wood, sand the leading and trail-
ing edges to the correct cross section. This
technique will ensure a uniform shape.
Leading edge cover:
Glue the four strips of the leading edge
cover(WP3688-24) in place, proceeding
from the leading edge to the forward spar.
After the glue is dry, sand the ends to con-
form to the wing’s shape and sand the
cover to a smooth surface. [Once again,
the advanced modeler may want to scal-
lop the rear edge of the cover.]
Separating the aileron:
Referring to Figures 3/4 and 3/5, cut
through the wing tip and ribs #7-13
between the rear spar and the torque bar,
and through the trailing edge between ribs
#6 and #14. A razor saw is recommended
for this. Remove the aileron by sliding the
torque bar from ribs #1-6.
Referring to Figure 3/5, sand the aileron
ribs to shape. Next, re-insert the torque
bar through ribs #1-6. Do not glue it.
Finally, glue the aileron hinges(Ni28-033)
to the rear spar where indicated.
Rigging:
Referring to Figures 3/9 and 3/10 and
Plan D02, use the bent pin again to bore
.5mm(.02î) holes through ribs #1, 4, 6, 9
and 12 for the rigging to pass through
against the spars.
Insert the compression bar(Ni28-018)
between ribs #9 and #10 on the lower
wing so it precisely aligns with the com-
pression bar on the upper wing and glue it
in place.
Each run of rigging line(WP1205)
between the solid ribs is attached at only
one end to a turnbuckle(W042). You will
use eight turnbuckles for each half of the
lower wing. The easiest way to run this
rigging is to tie off the two turnbuckles to
the inner side of rib #9, then run continu-
ous lengths of line from those turnbuckles
to rib #1. Each time the line emerges
through a rib, thread it through both holes
on a turnbuckle (instead of tying it off)
and proceed to the end of the run. Put a
small weight on the excess line to ensure
it is taut, then glue the line in place at rib
#1 and cut off the excess line. Thereafter,
slide the loose turnbuckles against the
appropriate ribs and glue them and the
line in place. Proceed more or less the
same way from the compression bar out to
rib #12. A daub of paint, matching the
turnbuckle, placed over the rigging line on
each turnbuckle will hide the line, if you
choose the continuous run method of rig-
ging.
Joining the wing halves:
Referring to Figure 3/7, glue the lower
wing joint(Ni28-034) to the right and left
lower wing halves, positioning casting
tight to the front spar. The finished wing
should line up straight across the leading
edge and with no dihedral.
