Traxxas 9785 ECM-2.5 Control Unit 1/18

Ö2 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.
