Step 11
Place the hatch cover into position in the flap opening.
Measure in 1/8" on all four sides of the hatch. Drill four
1/16” holes at the intersections of the lines as shown.
Note: Drill through the servo hatch and the
underlying hatch mounts. Use caution not to
accidentally drill through the top of the wing.
Step 12
Remove the servo hatch cover and re-drill the holes using
a 5/64" drill bit. Use 2–3 drops of thin CA to harden the
underlying wood. This will prevent the screws from
crushing the wood when they are tightened. Secure the
hatch using four #2 x 3/8" screws.
Step 13
Repeat Steps 1 through 12 for the remaining flap servo.
