Hello im trying to figure out if there is a address for Ace Servos and Hitec servos. i got some i got to mail in for some repair work so any advice would be helpful.

Have you thought of checking their respective websites?
Most manufacturers have their street addresses, and other contact information, available on their websites (try scrolling to the bottom of the page if need be).
