Step 8
Set the servo in place on the mounting block with
a 1/32-inch gap between the servo and the hatch
surface. Mark the servo mounting hole locations on
the blocks with a pencil.
Step 9
Remove the servo and use a 1/16-inch drill bit in a pin
vise to drill the mounting holes. Apply a small drop of
thin CA to each of the holes to strengthen the wood.
Allow the CA to cure without using accelerator.
Step 10
Use a #1 Phillips screwdriver and the hardware
provided with the servo to install it on the hatch. Be
sure to maintain a 1/32-inch gap between the servo
and the hatch surface.
Step 11
Use a hobby knife to trim the CA hinge where it
protrudes into the servo bay in the stabilizer. Be
careful not to puncture the upper skin.
