16. Apply 2–3 drops of thin CA in each hole drilled.
Also saturate the front and rear of the block using thin CA to
harden the block. This will help keep the block from splitting
when the servo mounting screws are installed.
17. Use the screws included with the servo and a #1
Phillips screwdriver to attach the servo to the mounting
blocks.
18. Fit the aileron servo and cover to the wing. Use
a pencil to transfer the four positions for the servo cover
mounting screws onto the cover rails.
19. Remove the cover and servo from the wing. Use a
pin vise and 1/16-inch (1.5mm) drill bit to drill the four holes
for the cover mounting screws. Make sure not to accidentally
drill through the top of the wing.
20. Use a #1 Phillips screwdriver to run a 2mm x 8mm
self-tapping screw in each of the holes to cut threads in the
surrounding wood. Remove the screw before proceeding to
the next step.
21. Apply 2–3 drops of thin CA in each hole to harden
the surrounding wood. This will help prevent the screws
from vibrating loose.
