Velineon VXL-3s Electronic Speed Control, waterproof (brushless) (fwd/rev/brake) The Velineon VXL-3s forward/reverse electronic speed control simplifies brushless technology with easy operation that gives you all the control you need for maximum fun. Quickly choose from 3 drive profiles in exactly the same manner as other Traxxas electronic speed controls (such as the XL-5). Profiles include: Sport, Race, and Training Mode (patented). Training Mode limits full-throttle power to 50% allowing young or new drivers to safely develop their control skills before unleashing the full-throttle capability of the Velineon system. High-frequency transistors and advanced circuit design deliver incredibly smooth and refined throttle control. High-current capacity (320 amps peak) and two-stage thermal protection frees you from motor limits. Super-flexible, high-current, low-resistance 12-gauge, wire acts like a series of giant pipes, flowing energy in and out of the VXL-3s electronic speed control and into the Velineon 3500 motor. The patented Traxxas Connector combined with Maxx cable is a better engineered solution for extracting all the power your battery has to give. Use Traxxas stock and hop-up replacement parts to get the most out of your Traxxas RTR vehicles. This product is made from high quality materials and designed for long-lasting performance. This is replacement hardware for use on Traxxas vehicles; consult your user's manual for exact parts listings.
