    Traxxas Bandit RTR VXL Buggy w/Brushless Motor

    The Fastest Ready-To-Race® Electric Buggy!     Extreme Brushless Horsepower! Top Speed: 70+mph!   The Bandit VXL expands the Extreme Sports Buggy Legacy with even more power than you ever thought possible. The new Velineon® Brushless Power System accelerates Bandit VXL into the stratosphere with jet-like thrust and incredible 70+mph top speed! The Bandit VXL is a low-slung, lightweight speed machine that’s rocket fast on pavement and rips incredible roost off-road. Get a pair of Bandits together and the race is on. Bandit VXL is a driver’s machine that will put your skills to the test with its mind-blowing top speed and lightning quick handling response. Out of the box, the Velineon Brushless Power System is optimized to put down the tire-melting horsepower, neck-snapping speed, and precision throttle response you expect from brushless. Most of all, it’s brushless done the Traxxas way: wicked fast and easy to use. Just plug it in for an instant rush of power and adrenaline. The Velineon Brushless Power system takes the guesswork out of enjoying the benefits of world-class brushless power. The system components work together as an optimized package, engineered from the start to deliver the ultimate in efficiency, speed, and run time. With the Bandit VXL, your battery selection determines your speed and skill level. Velineon accepts the widest range of battery types, including 3-cell Lithium Polymer packs (3S LiPo packs). These packs pump out over 11 volts of power for intense, skill level 5 speeds beyond 70mph! Nothing else even comes close. Built-in low-voltage detection in the VXL-3s™ Electronic Speed Control conveniently helps you maintain your LiPo battery packs in top condition. * Requires Optional Pinion Gear (sold separately).   The quest for ultimate speed began with the battery connector. As today’s batteries store more and more energy inside their cells, traditional battery connectors became a roadblock, unable to deliver all the energy the battery is capable of outputting. The new Traxxas High-Current Connector and Maxx® Cable 12-gauge wire opens the door for unrestricted current flow.   The Velineon® 3500 Brushless Motor is precision-matched for use in the 1/10th scale Bandit, delivering the perfect balance of brutal horsepower and efficiency. The sensorless design works with the sophisticated circuitry in the VXL-3s Electronic Speed Control for smooth starts and precise control, without the need for additional sensors and wiring. Since there are no brushes or commutator to cause friction and wear, Velineon brushless power is always fast, run after run.   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 (patent pending). 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. Bandit VXL’s performance can be tailored for drivers of any age and experience. High-frequency transistors and advanced circuit design deliver incredibly smooth and refined throttle control. With the VXL-3s you have the flexibility to use conventional brushed motors, brushless motors, and sensored brushless motors. The VXL-3s auto detects the motor type for you. High-current capacity (320 amps peak) and two-stage thermal protection frees you from motor limits.   The Bandit VXL is equipped to handle serious horsepower with features such as the advanced Revo®-Spec Torque-Control™ slipper clutch. The patent-pending design delivers smooth operation, precise adjustment, and consistent traction control, even when tortured with massive amounts of horsepower. New upgrades to the Bandit VXL include high-grade he
