The award-winning Traxxas Revo® 3.3 is an engineering triumph that delivers the ultimate in uncompromising performance, tuning, and durability. A vehicle so advanced, so innovative, nineteen patents were needed to cover it all. The new chassis layout borrows from the exclusive Revo Platinum Edition with race-inspired features such as a compact receiver box that includes an integrated personal transponder mount for race day. The legendary high revving power of the national championship winning TRX 3.3 Racing Engine drives a low mass 2-speed transmission for amazing acceleration and 45+mph top speeds. Time and time again, Revo has proven the benefits of its visionary design, and the newest Revo continues the legacy. It is the only truck to win six consecutive national racing titles!      The newest Revo keeps sharp focus on core performance elements as the lightest, quickest, and most versatile Revo yet. Only Revo has the latitude in performance and tuning adjustment to be both the pinnacle of monster truck performance and a superior racing platform. World-class Traxxas engineering sets Revo apart.
