racerdx6: If you're using the Old Skool front-end run the servo FLAT on the chassis. If you've got the 94145 airtronics bolt it make sure it's straight and centered, and bolt it down. I'd also recommend running a small bead of shoe-goo in front of and behind the servo where it meets the chassis. I have seen individuals move their servos within the slots in those mounts after a good hard hit.
