perpendicular with the servo case. Cut three arms from each
servo arm leaving one arm on each servo that matches
the photo. Enlarge the outer hole of each remaining arm
with a 5/64" [2mm] drill bit. Attach a 12" [305mm] servo
extension to each servo. Secure the connection using tape,
heat shrink tubing (not included) or special clips designed for
that purpose. Install the rubber grommets and eyelets onto
the servo mounting tabs.

CA to each hole to harden the surrounding wood. When the
CA has dried, install the servos into the openings as shown
using the screws supplied with the servos.
