A closeup of the stringers and the horizontal stabilizer mounting plates show that the horizontal
mounting plate outer has been notched for the stringers and the bottom has also been trimmed.
Bottom formers and belly pan parts have been added. The hatch rails on the left have been
contoured and the magnets added.
The cowl ring has five layers with four parts for
The cowl ring has been added and contoured.
The cowl has been sheeted with 1/32-inch
balsa. You can also see balsa “infill” behind
the cowl and around the canopy area. This will
allow for better covering adhesion.
Here you can see the composite main spar assembly. A 1/2 x 1/8-inch basswood plank has been
glued to the bottom of main spar A. The wing’s TE (from W- 10 and a lamination of 1/2 x 1/8-inch
balsa and 1/8-inch square basswood) assembly is below the main spars.

with the fit, bond it with wood glue.
Glue the wing mounting plate- 4
assembly into F- 6 and wing saddle
center into F- 6 according to the plans
and pin it to the board. Slide F- 3, F- 4,
IP, IPA, and F- 5 in place and glue when
it is ready. Slide the F- 2 and motor
box assembly into the front of F- 3 and
glue it in place with wood glue. Pin
F- 1 in place. Starting with the topmost
stringer (stringer 1), glue in place the
top four 3/16-inch square balsa stringers,
alternating on each side.
These stringers go from F- 1 to F- 8. On
stringers 5 through 7, you will need to
cut a notch in the horizontal mounting
plate outer to receive them. Add the
wing saddle outers following the plans.
Install stringer 8 and trim the bottom
of the horizontal mounting plate outer.
Stringer 9 should sit on top of the wing
saddle outer and go from F- 5 to F- 10.
Install the 1/4 x 1/8 magnets in the hatch
rail upper and glue them in place. Add
the remaining stringers on the top half
of the fuselage.
