Cut the six nose block laminations from 1/8" balsa. Also cut the two
nose block key pieces (part F1 on the plan). Note the grain direction
for each nose block piece. Glue all the pieces together. A piece of
1/8" dowel can be used to align the individual laminations. Remove
the dowel after gluing the laminations.

Cut the 1/2" x 1/8" tapered stock for the leading edge, and trailing
edge. Cut each piece a bit long for trimming after assembly. Lay
some plastic kithchen wrap over the plan. Glad Wrap works
especially well. Pin the LE and TE pieces to the building surface.

Bend the landing gear from .047" piano wire. Glue the landing gear
to part F2. Also glue part F2A to F2. When dry sand the face of
F2A so it is even with the landing gear wire.

Glue the landing gear assembly to the forward face of former F3.
Also glue in the gussets F4.

Rough shape the nose block using the plan as a guide. Place
the nose block on the fuselage and final sand the nose block
shape.

Build the stab and assemble the two fin parts.

F1 (2)

Sand the stab LE round and the TE to a taper on the top. Cover the
fuselage and stab. If you water shrink and dope the stab, be sure
they are pinned to a flat surface while drying. Two coats of 50-50
clear dope should be enough on the stab. Leave it pinned to a flat
surface for at least a week after doping before it is glued to the
fuselage.

Glue parts F13, F17, and F18 to the rear of the fuselage as shown.
Also add 3/32" balsa strips to the fuselage nose between cross
pieces 1 and 2.
