7. Position the servo on the blocks. Use a pencil to
mark the front block where it will need to be trimmed to
clear the servo lead.
8. Use a rotary tool and sanding drum to remove the
material from the block so the servo lead can clear the block.
9. Use a pencil to mark the locations for the four servo
mounting screws on the blocks.
10. Use a drill and 1/16-inch (1.5mm) drill bit to drill
the holes for the mounting screws.
11. Apply 2–3 drops of thin CA in each hole drilled.
Also saturate the top of the block using thin CA to harden the
block. This will keep the block from splitting when the servo
mounting screws are installed.
Important
: Do not use a CA accelerator. Using an
accelerator will not allow the CA to soak into the fibers
of the wood, hardening the blocks.
12. Use the screws provided with the servo and
a #1 Phillips screwdriver to attach the servo to the
mounting blocks.
13. Repeat Steps 2 though 12 to install the remaining
flap servo.
