22. Once you have the 1/16" [1.6mm] center sheeting
trimmed to fit around the landing gear rail, glue the sheeting
to the main spar, bottom of the ribs and the landing gear rail.
Trim the sheeting from over the receiver battery tray.
❏
23. From the third 8-1/2" [216mm] sheet, trim and glue
the aft center sheeting to the sub-trailing edge strip and the
top of the ribs.
❏
24. From the 1/16" x 1/4" x 24" [1.6mm x 6mm x 610mm]
balsa stick, cut and glue cap strips to the bottom of ribs
W-4 through W-7.
❏
25. Use a bar sander to sand the top and bottom leading
edge sheeting flush with the sub-leading edge.
❏
26. Glue the two 1/4" x 3/4" x 24" [6mm x 19mm x 610mm]
balsa leading edges to the front of the sub-leading edge.
❏
27. Using a razor plane and bar sander, round the leading
edge to match the wing cross-section.
❏
28. Trim the top sheeting from over the two alignment
slots in ribs W-1. The first slot is approximately 1" [25mm]
from the leading edge and the second one is approximately
5" [127mm] from the leading edge. A T-pin works great for
locating the slots.
C. Cut the hole for the landing gear rail slightly smaller.
Then, trim the sheeting to fit.
B. Position the sheeting against the aft edge of the
leading edge sheeting. Press down on the sheeting around
the landing gear rail. This will leave a chalk mark on the
sheeting.
