Mount The Fin - GREAT PLANES ElectroStreak Instruction Manual

D 6. Glue the stab to the stab saddle by applying thin
CA generously along both sides of the fuse. Also apply thin
CA in the fin notch and at the front and back of the stab to
insure that the glue fully penetrates into the joint. Finally,
add a small fillet of thick CA along both sides of the fuse/
stab joint to fill any gaps.

MOUNT THE FIN

IMPORTANT NOTE: Improper fin alignment is one of the most
common causes of poor flying airplanes. The fin absolutely must
line up with the centerline of the airplane! Therefore, use care in
the following steps to mount the fin properly.
1. Remember the fuselage centerline mark you made
D
at F-4? Now measure 3/32" left and right of that mark and
make two more reference marks. Now lay a straightedge
along the left side of the fin, with one end of the straightedge
on the left mark at F-4. Adjust the position of the fin until
it matches the straightedge.
D 2. Holding the fin in this position, draw lines on the stab
center on both sides of the fin for future reference. Double
check this by laying the straightedge along the right side of
the fin and holding it on the right mark on F-4.
D 3. Hold the fin in place on the stabilizer and line it up
with the marks you just made. Check to make sure the fin
is perpendicular to the stab, using a draftsman's triangle or
a carpenter's square. Apply a couple drops of thin CA to
tack glue the fin in place.
D 4. Double check the fin alignment (It must line up
with the fuselage centerline), then apply thin CA all along
the base of the fin. Use thick CA to fill any gaps.
5. Cut the die-cut "bumps" off the dorsal fin parts.
D
6. Sand the top edge of the dorsal fin to a rounded
D
shape.
D
7. Align the dorsal fin on the fuselage centerline in
the same manner as used for aligning the fin. and glue it to
the fuse top and fin.
