INSTALL THE TAIL SECTION

1. Insert the horizontal stabilizer into the stabilizer slot and
center it left and right. Align the stab so the distance between
the wing tips and stab tips are equal on both sides. Now, with
the wing still in place, stand behind the model approximately
10 feet [3m] and confi rm that the stab sits parallel with the
wing. If not, weight can be added to to the high side while
gluing the stab in place, or the stab pocket can be lightly
sanded until the stab and wing sit parallel.
❏
2. With the stab carefully aligned from the previous step,
use a fi ne felt-tip pen to trace the outline of the fuselage onto
the stab. Mark the top and bottom of the stab.
Pull the stab from the fuselage and remove the covering 1/16"
[1.6mm] inside your lines using the same technique you used
on the wing.
❏
3. Coat the exposed wood with 30-minute epoxy (although
messy, a more reliable glue joint can be attained if you also
coat the inside edges of the stab pocket). Reinstall the stab and
properly position it in the pocket. Wipe away any excess epoxy
with denatured alcohol and let the epoxy cure undisturbed.
When cured, the wing can be removed from the fuselage
and set aside as it will not be needed until the fi nal set up
of the plane.

4. Stick a T-pin or something simliar through the center of
six CA hinges. Insert the hinges into the slots in the trailing
edge of the stab up to the pins. Install the elevator halves
onto the other ends of the hinges. Allow approximately 3/32"
[2.4mm] gap between the ends of the stab and the elevators.
Pull the pins out, defl ect the elevator halves down and apply 6
to 7 drops of thin CA glue to the center of each hinge. Flip the
plane over and apply another 6 or 7 drops to the undersides
of the hinges. When the CA glue has dried, pull on each
elevator half to confi rm they are thoroughly glued in place.
