TSM (Traxxas Stability Management) is an electronic active handling system that uses sensors to understand the movement of the vehicle compared to the driver’s input and applies steering corrections as needed. This makes any TSM equipped vehicle much easier to drive, requiring less skill for precise control. The benefit is most visible with difficult to control models such as powerful 2WD brushless models on loose dirt, water, smooth pavement, and even snow and ice. Braking with 2WD models is dramatically improved as TSM works to keep you arrow straight until you come to a complete stop.
