lines). Making sure the stabilizer is in proper alignment (use your cen-
ter marks plus a triangle to make sure it is perpendicular to the fin),
On the top of the fuse-
lage, about 10" from the
rear, there is a pre-drilled
hole for the elevator's
outer nyrod to exit. Cut
away the covering material
from this hole. By the same
token, there is a slot in the
left side of the fuselage,
about 3" from the rear. Cut
away the covering from
this slot.
Position the vertical
fin on the top rear of the
fuselage so it is flush with
the rear and centered on
the fuselage. With a pencil,
mark the outline of the
base of the fin on the top of
the fuselage.
Cut away the covering
film from the top of the
fuselage about 1/16"
INSIDE the mark.
Epoxy the fin onto the
fuselage, making sure it
remains vertical.
Install the rudder using
the three furnished hinges
in the pre-cut slots. CA the
hinges in the same manner
as you did for the ailerons.
Repeat the process and
hinge the elevator to the
stabilizer.
Mark the center on the bot-
tom of the stabilizer at both the
leading edge and trailing edge.
Turn the fuselage over and
block up the wing saddle so the
top of the fin will rest on the
bottom of the stabilizer. Make
sure the wing saddle remains
parallel with your work surface.
The trailing edge of the fin
should line up with the trailing
edge of the stabilizer (hinge

Install the two outer nyrods. They will be for the elevator and rud-
der linkage. To do so, work from the rear to the front. Start with the
longest one which is for the elevator. Cut off one end at about 45
degrees. Thread the angled end through the hole in the top rear of the
fuselage, then through the hole in the LEFT side of the rearmost fuse-
lage bulkhead. Continue the nyrod forward and thread it through the
hole on the LEFT side of the next bulkhead. Leave about 4" of nyrod
behind the leading edge of the stab.

Repeat for the rudder nyrod. It goes through the slot in the side
of the fuselage. It is tricky to hit the large hole that is in the bulkhead
behind the access hatch. Use a piece of .045 or 1/16" music wire first
to "fish" through the hole then follow it with the nyrod. Continue the
nyrod on through the holes in the RIGHT side of the next bulkhead.
Continue it forward, threading it through the hole in the RIGHT side
of the next bulkhead. Leave about 1" sticking out of the fuselage side.
When done, the rudder's nyrod should be on the right side of the fuse-
lage so it corresponds to the nosegear linkage.
Reminder: before gluing, make sure the rudder nyrod ends up on
the RIGHT side of the fuselage and corresponds with the nosegear
linkage.

use a pencil to mark where the
fin meets the stabilizer. Being
very careful NOT to cut into the
balsa wood, score and remove
the covering material 1/16"
inside your marks. Epoxy the
stabilizer to the fin, maintaining
proper alignment.
