RE: Sig Kougar Build
Part 3
You must turn the wing over and cut a trench to run the servo wire. I cut about 5/8" trench V cut with a new #11 blade on each side.
You can barely see it but I made a tube to pass the servo wire through with regular paper. This way I can replace the servo without tearing up the wing.
I forgot mention be careful when removing the wing skin and foam. Yes, you must remove both you will not be able to remove just the wing skin. After you glue the tube you can trim some foam and re-glue the wing skin and foam you removed to run the trench.
