 1. Separate the rudder from the vertical fin. Set the
rudder and hinges aside at this time.
 2. Place the fin on the fuselage. Use a ruler to
align the rear edge of the fin to the rear edge of
the fuselage.
 3. Check the alignment of the fin to the
stabilizer. Since both the fin and stabilizer are
tapered, you won’t be able to use a square to
accurately set the angles during this step, but it
will help gauge the angles.
Check that both angles are equal
 4. Once the alignment has been checked, mix 1/4
ounce (15mL) of 30-minute epoxy and apply it to
the bottom of the fin where is contacts the fuselage.
Use low-tack tape to hold the fin in alignment
until the epoxy fully cures. Use a paper towel and
rubbing alcohol to remove any excess epoxy before
it has a chance to cure.
 5. Once the epoxy has cured between the fin and
fuselage you can install the fin fairing. Use 30-minute
epoxy to glue the fairing in position. Use low-tack
tape to hold it in place until the epoxy cures. Use
a paper towel and rubbing alcohol to remove any
excess epoxy before it has a chance to cure.
