Carl Goldberg GBGA1072 - Manual (Page 7)

Using the fin as a guide, mark
the top of the stabilizer so you will
know where the front edge of the fin
stops. (Notice that the notch you cut
earlier is flush with the trailing edge
of the stab, which is ¼” in from the
rear of the fuselage.)
Using a straight edge, draw a
line down the center of the stab from
the mark you just made to the
trailing edge of the stab. Remove the
covering 1/16” out on each side of
the centerline. Be careful not to
remove the covering forward of the
front of the fin.
Mix a small amount of 5-
minute epoxy and spread a thin coat
on the stab where you removed the
covering. Using a square, set the fin
in place and hold with masking tape
until dry. The front of the notch in
the fin you cut earlier should be even
with the rear of the stab.
Locate the elevator and four (4)
hinges.
Install the hinges in the pre-cut
slots in the elevator and slide them
into the slots in the stab trailing edge.
Leave about a 1/32” gap (a
matchbook cover makes an ideal
gauge). Apply 2-3 drops of thin CA
glue to both the elevator and stab
side of all the hinges. When the CA
is dry, flex the elevator back & forth
to loosen it up.
