9. If you’re building the conventional straight-
tail, build the fin using the 1/8" x 1/8" balsa sticks
and the 1/8" x 1/4" balsa sticks leftover from
building the stab halves. Use leftover 1/8" balsa to
make the tip of the fin.
❏
1. If you’re building the V-tail version, bend the
joiner wire as shown on the plan. When you bend
the wire, clamp your pliers over the brass bearing
tube next to the horn. Hold the joiner wire over
the plan to make sure you have bent both sides
the same.
❏
2. Use sandpaper to roughen both brass bearing
tubes on the joiner wire so glue will adhere. While
you’re at it, roughen the joiner wire where it will
be glued to the elevators.
❏
3. Carefully add a small drop of oil to the joiner
wire on both sides of the horn to lubricate the
bearing tubes. Refrain from getting oil on the
outside of the bearing tubes.
❏
4. Glue the balsa stab mounts together with
the joiner wire in between. Make sure you have
the joiner wire facing the right way and make sure
you glue the bearing tubes to the mounts, but
refrain from getting glue inside the bearing tubes.
❏
5. Sand the top of the stab mount to the airfoil
shape shown on the plan.
❏
6. Test fit both stab halves to the joiner wire
and the stab mount. Position the stab halves so
they are centered on the stab mount and are even
with each other. View the stab from the rear and
make sure they are both in the same plane. If
necessary, remove the stab halves and use pliers
to
tweak the joiner wire so both stabs are even.
