The clean, modern hull design is built up in layers for maximum rigidity where it matters most, the transom and ride pad. The integrated battery trays securely hold a variety of battery configurations—from the included 7-cell Power Cell NiMH packs to 3S LiPos. Ride trim is easily adjusted by positioning the packs fore and aft using the convenient hook and loop straps that secure the batteries. The optimized rudder configuration carves amazing full-throttle turns. A high-output 2.4GHz radio system, along with water-cooled and waterproof electronics, keep Spartan going for the trouble-free, all-day running you count on from Traxxas.
