10. Temporarily join the elevators with the joiner wire. The
joiner wire will be easier to install if you chamfer (bevel) the
ends a little. If necessary, "tweak" the joiner wire so the
elevators are parallel and lay flat on your building table when
the joiner wire is installed. If you found it necessary to
"tweak" the joiner wire, use a felt-tip pen to mark it so you
can install the joiner wire in the same orientation when you
permanently join the elevators.
Build the Fin & Rudder
1. Cover the fin/rudder portion of the plan with waxed
paper or Plan Protector.
2. Pin the die-cut 3/16" [4.8mm] balsa fin frame V-6 in
position on the fuse plan. From one of the 3/16" x 3/8" x 24"
[4.8mm x 9.5mm x 609.6mm] balsa sticks, cut and glue a LE
and TE to V-6. Cut and glue a fin base, along the bottom of
the fin, between the LE and TE. Also, cut and shape a LE fin
fillet at the bottom of the LE. Note: Cut the TE so that it
extends to the top of the stabilizer.
3. From the 3/16" x 3/16" x 30" [4.8mm x 4.8mm x 762mm]
balsa stick, cut and glue the fin ribs to the frame. Note that
one of the ribs is glued to the top edge of the fin base.
4. Remove the fin from your building board. Inspect all the
glue joints and add CA to any joints that don't look strong.
Fill any gaps with balsa sanding dust and a drop or two of
thin CA.
5. Build the rudder frame from the die-cut 3/16" [4.8mm]
balsa R-7, R-8, R9 and R-10 frame pieces and a 3/16" x
3/8" [4.8mm x 9.5mm] balsa stick.
6. From the 3/16" x 3/16" x 30" [4.8mm x 4.8mm x 762mm]
balsa stick, cut and glue the rudder ribs to the frame.
7. Remove the rudder from your building board. Inspect
all the glue joints and add CA to any joints that don't look
strong. Sand the rudder and fin to shape using the fuse plan
as a guide. Sand both sides of the rudder and fin flat and
even. Be careful that you don't sand any area too thin. Do
not sand the bevel on the LE of the rudder until after the
hinges have been installed.
8. Lay the fin and rudder over the plan and lightly mark
the hinge locations on the LE of the rudder and the TE of the
fin. Repeat the process to mark the hinge locations on the
LE of the elevators and TE of the stab.
