The all new Traxxas Blast was designed and engineered to be reliable, fast, and easy to drive. The pre-installed water cooling system for the motor helps keeps the Blast cool for all day fun and longer run times. With the fully proportional, waterproof Nautica electronic speed control, patent-pending watertight receiver box and the waterproof high-torque servo, the lakeside fun doesn't end early because of wet radio gear. Best of all, the Traxxas Blast is fully-assembled and ready-to-run, with the electronic speed control and radio system installed. You'll be challenged by the waves, not an assembly manual. Blast's colorful decals and simple operation get you out on the water and having fun, fast!
