The wing can be removed at this time to allow
the fuselage to be easier to manage during the
remainder of the assembly of your model.
 1. Remove the rudder from the fin. Set the rudder
and two CA hinges aside until later. Place the fin in
the slot on the top of the fuselage. Use a felt-tipped
pen to trace the outline of the fuselage on the
bottom of the fin.
When cutting through the covering, use a new
#11 blade and light pressure to avoid cutting into
the underlying wood, which could weaken the
underlying structure, causing it to fail in flight. We
also recommend using a hot knife to melt through
the covering to help reduce damaging the wood.
 2. Remove the fin from the fuselage. Use a hobby
knife and #11 blade to trim the covering below
the lines drawn in the previous step by 1/16 inch
(1.5mm). Remove the covering, exposing the bare
wood. Leave a 1/4-inch (6mm) piece of covering
at the hinge line to add a finished look to your
model when the fin is installed. The lines can be
removed using a paper towel and rubbing alcohol.
 3. Place the fin back in the slot on top of the
fuselage. Use a square to make sure the fin is
positioned 90 degrees to the stabilizer. If not,
lightly sand the inside of the filler blocks that form
the slot to correct its alignment.
 4. Use a straight edge to make sure the fin is
aligned with the rear of the fuselage.
Do not use CA accelerator when gluing the
fin to the fuselage. The CA must be allowed
to soak into the fuselage and fin for the
best bond between the two surfaces.
 5. Once aligned, wick thin CA into the joint
between the fin and fuselage. Allow the CA to fully
cure before proceeding.
