The Spartan is still the reigning king of brushless RC race boats, but none other than the Slash 4X4 gives it a run for its money. Spartan Product Info: 4X4 wTSM Product Info: : For this run we used a stock Slash 4X4 with Traxxas Stability Management and included optional high-speed gearing with a Traxxas Power Cell 3s LiPo. We installed aftermarket paddle tires to propel across the water. We also secured pre-cut foam noodle sections for flotation – just in case. Vehicles shown are being operated by professional drivers in a controlled environment. For the safety of users, others, and the product, please do not imitate the maneuvers performed in this video.
