Technical Performance

The Spartan SR VXL represents the culmination of Traxxas's expertise in high-performance marine RC engineering. At 36.5 inches in hull length with a 9.5-inch beam, the boat achieves a perfect balance between the length needed for planing efficiency and the width required for stability in turns. The vacuum-formed ABS hull features a 26-degree deadrise angle—the upward angle of the hull from the centreline—which is the optimal angle for high-speed water boating, providing the sharp entry needed for speed whilst maintaining the lift characteristics that keep the boat stable when running at maximum velocity. The overall assembled length reaches 40.8 inches, and with a weight of just 5.29 pounds (2.40 kg) without battery, the boat is light enough to achieve rapid acceleration whilst remaining substantial enough to cut through choppy water with authority.

The electrical system combines Traxxas's proven VXL-6s Marine electronic speed control with the potent Velineon 540XL Marine brushless motor rated at 1850 kV. This motor generates tremendous power output whilst remaining compact enough to fit within the boat's efficient hull design. The water-cooled jacket ensures that even at full throttle, the motor operates at safe temperatures despite the intense demands of high-speed boating. The system accepts dual 2S or 3S LiPo battery packs, or dual 7-cell NiMH batteries, providing flexibility in choosing your power source based on your budget, charging preferences, and desired runtime characteristics. The 42-millimetre, two-blade composite propeller features a 59-millimetre pitch—the distance the prop theoretically advances in one complete rotation—which is precisely calibrated to utilise the motor's power curve most efficiently whilst achieving the advertised 50+ mph top speed. The direct drive system with its 4.7-millimetre flex cable delivers mechanical efficiency without the losses inherent in traditional multi-stage transmission systems, allowing more of the motor's power to translate directly into forward motion through the water.
