How to Calibrate Traxxas Electronic Speed Controls
Your Traxxas electronic speed control may require periodic calibration to maintain optimal performance. If your vehicle stops responding to throttle input, if you would like to change to a different mode, or if you switch from NiMH batteries to LiPo batteries you will need to go through these programming steps.
These programming steps are the same for the XL-2.5, XL-5, XL-10, EVX-2, VXL-3s, and VXL-3m.
