Technical Performance

The X-Maxx Ultimate represents a masterclass in RC truck engineering, combining a 1/6 scale platform with genuine 50+ mph top speed capability when running dual 4S LiPo batteries with optional gearing. The Velineon 1200XL brushless motor delivers instant, smooth power delivery with zero maintenance requirements compared to traditional brushed motors, whilst the waterproof VXL-8s speed control integrates sophisticated telemetry systems that provide real-time data logging and performance analysis. With a total length of 30.67 inches, front and rear track of 21.3 inches each, and a substantial kerb weight of 22.20 pounds (or 25.06 pounds fully loaded with batteries), this truck commands serious presence and stability. The single-speed transmission delivers an 8.11:1 overall drive ratio from the stock configuration, with sealed hardened steel bevel differentials providing limited-slip functionality for balanced power distribution. The vehicle's 4.2-inch ground clearance combined with 7.4-inch shock lengths and massive 8.4-inch belted Sledgehammer tyres allows for extraordinary obstacle traversal and suspension travel. Battery compatibility includes dual 3-cell or 4-cell LiPo packs equipped with Traxxas High Current Connectors, with the battery tray measuring 197mm × 52mm × 44mm. The electronic braking system provides smooth, proportional deceleration, whilst the shaft-driven 4WD system with CV driveshafts ensures durability and traction across all terrain types. The TQi 2.4 GHz radio system with factory-installed Traxxas Link wireless module operates on digital 2.4 GHz frequency with two channels and integrated Stability Management, providing precision control with zero frequency conflicts even in crowded RC environments.

Frequently Asked Questions

• What is the top speed of the Traxxas X-Maxx Ultimate 8S monster truck? — The X-Maxx Ultimate achieves 50+ mph with two 4S LiPo batteries and optional gearing. The actual top speed depends on your specific battery choice, gearing setup, driving surface, and weather conditions, but this truck is genuinely one of the fastest large-scale RC monster trucks available in the UK market today.
• Is the X-Maxx Ultimate suitable for beginners? — This is an advanced RC truck designed for experienced enthusiasts with skill level 5 rating. Whilst it comes ready-to-run, it requires understanding of LiPo battery safety and maintenance, proper charging procedures, and familiarity with high-performance RC vehicle handling. Beginners should consider starting with a more entry-level brushless RC car before progressing to this level of complexity and power.
• What batteries does the X-Maxx Ultimate need? — The X-Maxx Ultimate requires two 4-cell (4S) LiPo batteries equipped with Traxxas High Current Connectors, wired in series for 8S operation. Traxxas recommends 6700 mAh or greater Power Cell LiPo batteries with iD (part 2890X). The battery tray measures 197mm × 52mm × 44mm. You can also use two 3-cell (3S) LiPo batteries if preferred, though this will reduce performance.
• How long does the battery last on the X-Maxx Ultimate? — Battery runtime depends on your driving style, terrain, battery capacity, and gearing setup. With recommended 6700 mAh 4S batteries, expect approximately 15-20 minutes of continuous driving under normal conditions, though aggressive full-throttle driving will reduce this to around 10-15 minutes.
• What charger do I need for the X-Maxx Ultimate? — The Traxxas EZ-Peak Live Dual 4S-capable charger (model 2973) is recommended, providing safe iD LiPo battery charging with integrated balancing and telemetry feedback. This charger can simultaneously charge two 4S batteries, cutting your charging time in half.
• What is included in the box and what do I need to buy separately? — Included: the truck itself, VXL-8s ESC, TQi 2.4 GHz radio with Traxxas Link module, and maintenance tools. You must purchase separately: two 4S LiPo batteries (6700 mAh minimum recommended), a compatible LiPo charger, and four AA batteries for the transmitter. Optional accessories include the Dual 4S LiPo Completer with EZ-Peak Live charger and the X-Truck LED Light Kit.
• Is the VXL-8s electronic speed control waterproof? — Yes, the VXL-8s ESC features complete waterproof construction, allowing confident operation in wet conditions, water crossings, and muddy terrain typical of UK weather and off-road environments. However, extreme water submersion should still be avoided.
• What is Traxxas Stability Management (TSM) and why does it matter? — TSM is Traxxas's advanced traction control system that automatically optimises throttle and braking to prevent spinouts, loss of traction, and control loss during aggressive acceleration, hard braking, and high-speed cornering. This technology makes the truck significantly easier and safer to drive at extreme speeds, preventing crashes caused by oversteer or understeer.
• Can I use the Traxxas Link wireless module to monitor my truck's performance? — Yes, the factory-installed Traxxas Link wireless module enables real-time telemetry monitoring via the free Traxxas Link app on your mobile device. You can view speed, RPM, battery voltage, temperature, and other data, and make micro-adjustments to transmitter settings without needing to connect to a computer.
• What size are the Sledgehammer belted tyres and why are they special? — The Sledgehammer belted tyres measure 8.4 inches diameter by 4.0 inches width (203mm × approx.). They feature a unique belted construction that prevents tyre ballooning at high speeds, maintains consistent shape for larger contact patch and better grip, and incorporates a wide open-block tread design that resists mud and debris clogging, ensuring superior handling and traction in all conditions.
• What is the overall size and weight of the X-Maxx Ultimate? — The truck measures 30.67 inches in length, 21.3 inches in both front and rear track width, and 13.99 inches in ride height. The wheelbase is 18.92 inches and the truck has 4.2 inches of ground clearance. Total weight is 22.20 pounds (9.5kg) without batteries, or 25.06 pounds (11.39kg) when equipped with two 4S 6700mAh LiPo batteries.
• How does the X-Maxx Ultimate compare to the standard X-Maxx Belted model? — The X-Maxx Ultimate is the premium version featuring substantially upgraded aluminium components throughout the suspension, chassis, drivetrain, and steering systems for enhanced durability and performance. It comes with the Traxxas Link wireless module as standard for telemetry monitoring. The standard X-Maxx Belted is the entry-level 8S option with fewer aluminium upgrades but still excellent durability and performance.
• What is the servo torque and response time? — The high-output metal gear steering servo delivers 450 oz-in of torque and responds in 0.17 seconds per 60 degrees at 6.0 volts, providing sharp, accurate steering response even at extreme speeds.
• Can I upgrade the drivetrain and gearing? — Yes, the X-Maxx Ultimate features modular design allowing for drivetrain upgrades and alternative gearing ratios. The stock configuration delivers 8.11:1 overall drive ratio. Optional gearing is available separately from Traxxas to optimise the truck for different driving styles, terrain, and performance priorities.
