This Super-Duty XR electronic speed control (ESC) with reverse from Novak will give you all the power you could ever hope for. It can handle low single and dual motor turn limits as well as 6-14 cells (works with two 6 or 7 cell packs). The Super-Duty XR has smart braking circuitry which means that if you try to go into reverse, the ESC will slow down the vehicle until it is a safe speed to switch to reverse. It also has reverse disable circuitry which allows you to disable the ESC's reverse capability. Features polar drive, radio priority, and digital anti-glitch circuitry. Includes heat sinks. Part number: NOV 1865.
