3. From left over 3/32" x 3" [2.4 x 76mm] balsa
sheeting cut two pieces to a length of 3-1/2".
❏
4. Set the former in place against former F2T. Do
not glue it in place! Fit one of the 3/32" x 3" x 3-1/2"
[2.4 x 76 x 89mm] balsa sheets to the former and the
wing. Do this for the left and right side. When you are
satisfied with the fit, glue the former to the wing and
the balsa sheets to the former and the wing. After
they have been glued in place, feather the wing
fairing sheeting and wing together with balsa filler.
❏
5. Fill the small open area under the leading edge
of the wing with leftover balsa. Do this on both sides
of the fuselage.
Assemble and Install the Landing Gear
❏
1. Locate the two prebent wire landing gear wires
and one of the coils of wrapping wire. Make a wire
wrapped joint at each end and the middle of the main
landing gear wire where shown on the plan. If you
are new to making and soldering this type of a joint,
refer to the Soldering Hot Tip below.
HOW TO MAKE A WRAP AND SOLDER JOINT
A. Bring the two pieces of landing gear wire together.
Clean the wire where they make contact with each
other using 300-grit sandpaper. After cleaning the
wire, bring the two pieces of landing gear wire
together where you want them joined. With a 6"
[152 mm] piece of soft wire begin by laying the wire
parallel to the landing gear wires that you will be
joining. Then make a 90º bend in the end of the wire.
B. Bend the soft wire around the two landing gear
wires being joined together. Continue to wrap the
soft wire around the landing gear wires until you
have approximately 20 turns of the soft wire
around the landing gear wire.
C. Bend the portion of the wire that was lying
perpendicular to the landing gear wires being
joined forward towards the wraps of soft wire. This
will prevent them from unraveling.
D. Cut the excess wire but leave enough folded
over the wraps of soft wire to keep the wire
in place.
