ST26. Trim the elevator torque rod blocks and
any protruding hinge blocks
so
they are even with
the bottoms of the ribs.
ST27. Reinforce any glue joints that do not
look strong.
ST28. Glue the elevator skins to the bottom of
the elevators
so
the trailing edges align.
ST29. Glue the stab skins
to
the bottom
of
the
stab.
If
you have not used any accelerator on the
stab you may glue the skins on with thick or
medium CA. Otherwise, use aliphatic resin. Work
over a flat work surface and be careful not to add
any twist into the stab as you press the skins to the
stab frame.
Optional:
Use the die
-
cut
1/8"
balsa
straight tail stab cradles
S2T
and
S7T
to hold the
stab flat on your workbench while you glue the
bottom skins on. Use the stab cradles the same as
the wing cradles shown in steps

on page 30.
ST30. After the glue dries, use a bar sander with
150
-
grit sandpaper to sand the sheeting even with
the ends of the stab and elevators.
ST31.
Cut the ribs and separate the elevator
from the stab. Sand the excess sheeting and rib
stubs from the TE of the stab and the LE of the
elevator. Sand the elevator sheeting even with
rib SIAS.
ST32. Glue a die

the TE
of
both stab halves. Glue a die

(also

to the
LE
of both
elevators.
ST33. Sand the stab TE's and the elevator LE's
so
they are even with the ends of the stab and
elevators. Sand the stab TE and elevator
LE's
so
they blend with the tips and skins.
ST34. Use
two
T
-
pins, placed in the
center
of
the leading edge of one of the elevators near the
ends, to align a straightedge and draw a centerline
with a ballpoint pen.
ST35. Mark the other elevator and the TE of the
stab the same way.
ST36. Cut the hinge slots on the centerlines of
the elevators and the stab where shown on
the plan.

ST37. Cut six
hinges
from the 2

strip
as shown in the sketch. Snip the corners off
the hinges
so
they go into the slots easier.
Temporarily join both elevators to the stab with the
hinges.
If
necessary, adjust the hinge slots
so
the
elevators and stab align.
ST39. Skip ahead to
Make the stab tips

to make the tip blocks (the straight tail and

tail tips are shaped the same way). When you're
done, return to step ST40.
ST40. Using the plan, accurately mark the
location of the

wire
and horn
(from now on referred to as just the
elevator
joiner)
on the elevators.
ST38. Locate the 3/4" shaped balsa
stab tip
ST41.
Drill
a 9/64

hole and cut a groove in the
center of both
LE's
for the joiner. Test fit the
elevator joiner in the elevators.
Hint:
Use a
1/8"
brass tube sharpened at one end
to cut the grooves.

The tip blocks match the

so
use the plan to reshape them to fit your straight
