- The Motor Controller (sometimes called an ESC - Electronic Speed Control), lives inside the vertical tube in an ES4. It is the main brain of an ES4, and syncs the battery, controls, and motor. If you have an issue with an ES4, a new motor controller will most likely fix it (ask us and we'll troubleshoot with you!)
