Once the glue on the rudder spine is dry, trim
the edges of the spine to match the contour of
the rudder. You can use a hobby knife or a
hobby saw to remove the majority of the
material and then finish shaping it with
sandpaper.

Finally, fit a triangular piece to the top and one
to the bottom. Once in place bond them in using
thin CA adhesive. If any gaps result fill them in
using thick CA adhesive.

Before you bond the vertical stabilizer
reinforcement pieces you need to install the
servo. The servo will be bonded in position in
the inside of the vertical stabilizer.
}}}}
Find the best location for your servo making
sure it will not interfere with the existing
plywood spar located inside the vertical
stabilizer or with the stabilizer reinforcement
components you will be bonding in after the
servo is mounted.

The following picture shows the recommended
orientation, though others may work
Locate servo and cut slot for servo arm exit
}}}}
Once you are happy with the location of the
servo, use a pen to mark the location of the
servo arm slot on the rudder.
}}}}
Tip, for the best servo operation you want to
install the servo so that the control arm runs at
90º to the hinge line as shown by the cutout in
the picture above.
