TRA9785 ECM-2.5 Electronic Control Module, waterproof (low voltage detection, fwd/rev/brake) (Traxxas)

ECM-2.5^™ features low voltage detection for 2s LiPo batteries and EZ-Set^® one-button programming to select driving modes. Choose Sport Mode for all-around driving, or Trail Mode for smooth drag braking on steep descents. For a smooth scale look while creeping over technical terrain, Crawl Mode applies full brakes the instant the throttle is released and allows drivers to continue through to reverse without a second push on the trigger.
