D 2. Glue two die-cut 3/32" balsa forward belly pan sides
together for both sides of the belly pan. Glue these
assemblies to the bottom of the wing, flush with the inside
of the lines you just drew, touching F-2.
D 3. Fit the die-cut 3/32" balsa forward belly pan filler
between the two belly pan sides and the LE of the wing.
The top of the filler piece must be flush with the top edges
of the belly pan sides.
D 7. Razor plane and sand the aft end of the bottom cowl
block to blend with the belly pan. The shaping should start
at about the location of the firewall. Sand the bottom two
corners to match the radius shown on the cross section of
the plans.
D 8. The remaining piece of belly pan sheeting should
be 5-1/4".
(ACTUAL SIZE)
D 4. Cut a 3/32" x 2" x 15" balsa sheet in half to make two
7-1/2" pieces. Edge glue two 3/32" x 2" x 7-1/2" balsa belly
pan sheets together. Cut 2-1/4" from the 7-1/2" dimension.
Sand a taper across the aft 1" width of the 2-1/4" sheet.
The taper should look like a chisel point.
D 5. Glue the 2-1/4" belly pan sheet to the side pieces,
forward filler, and the wing sheeting.
D 6. Use the lines you drew in step 1 to sand the sheet to
the correct width.
(NOT ACTUAL SIZE)
D 9. Draw a line 2" from one end, across the 4" width.
Sand the sheet to a chisel point, tapering from the line to
one edge.
D 10. Glue the two die-cut 3/32" x 5" aft belly pan sides
along the inside edges of the lines drawn on the wing. The
wide end should be touching F-4. Refer to the fuse plans,
then lightly sand the aft belly pan sides to maintain a
straight line from the aft fuse bottom when the sheeting is
applied. Glue the die-cut 3/32" balsa rear filler between the
two sides and the wing.
