Mario, I never run servo savers on my models anymore. Most high torque servos have enough power to overload the savers anyway. I just make direct connections using home made drag links with 3mm threaded rod and standard Traxxas rod ends. Make them any length you need, and the steering has a much more direct and solid feel to it, with a lot less slop.

Just my 2 cents!
