what is best to use on the servo arm screw to keep it from backing out? (metal gears). If loctite whar color.

You shouldn't need to use anything to keep it in place. Screw it in tight and you will be fine.

only if the screw included a star washer, most of the older MG servos did not and require lock-tite and the blue is what you want to use.

Ken

I did. I was thinking of the good ole nylon/plastic control horns. That'll teach me to slow down as I read the forums!!
