faces the leading edge (tape) of the cover. With a small gap
between the cover and servo, use a felt-tipped pen to mark
the locations of the servo mounting screws on the mounting
tabs.
23. Remove the servo from the cover. Use a drill and 1.5mm drill
bit to drill the holes for the servo mounting screws.

provided with the servo. Center the servo and place the arm
on the servo perpendicular to the servo centerline. Remove
any unused arms so they won't interfere with the operation
of the servo.
