Pro-Line Big Hit Servo Saver Kit
Here is a very cool product from Pro-Line, the Big Hit Servo Saver Kit. Why do you need one? In ultra-demanding applications like rock or monster truck racing, a soft servo saver makes your truck sloppy to drive, but not running one at all can result in broken servos. The P-L Big Hit is designed to give you precise steering while giving your expensive servo the protection that it needs.
