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.
