Traxxas X-Maxx Monster Truck RTR 8S Capable (Green)

Traxxas X-Maxx Monster Truck is a large-scale, ready-to-run monster truck built for high-speed bashing and heavy-duty trail abuse. It’s 8S-capable for extreme top speeds (50+ mph with two 4S packs and the optional spur gear), comes with the TQi radio system and Traxxas Link telemetry, and packs a rugged shaft-driven 4WD driveline designed to handle big power and rough landings.

Key Features

• 8S LiPo compatible — supports high-voltage battery setups for maximum speed and acceleration.
• 50+ MPH capable with two 4S batteries and the included optional spur gear for extreme runs.
• 5 mm output shaft on the motor for solid power transfer.
• Aluminum slip-on heat sink helps draw heat away from the motor.
• Dual motor cooling fans keep temperatures down under heavy load.
• Traction control helps prevent spinouts and reduces loss of control in slippery conditions.
• Adjustable traction control — set assistance from off up to 100% from the transmitter.
• Traxxas Link enabled for real-time telemetry and easy tuning via smartphone.
• 2.4 GHz 5-channel micro receiver (6533) with fail-safe security and integrated telemetry ports for reliable radio performance.
• Automatic model storage — stores and loads settings for up to 30 Traxxas Link-enabled models for quick switching.
• Multi-function knob on the ESC for in-field adjustments.
• Adjustable steering and throttle percentage (dual rates) for dialing control to your taste.
• Built-in cooling fan on the speed control for steady operation.
• Adjustable steering and throttle sensitivity (exponential) to refine response.
• BEC voltage and motor temperature sensor installed for telemetry feedback and safer operation.
• Quick one-hand battery access with a pivoting rear latch mechanism for fast changes.
• Real-time telemetry via Traxxas Link for temperature, voltage, and more.
• Machined heat sinks for improved thermal performance on electronics.
• 10-gauge silicone wire for high-current, flexible power delivery.
• Integrated protection circuits to help prevent electrical damage.
• LED status lights for quick system checks.
• "Big Block" brushless motor — a 4-pole 1275 kV unit that delivers strong, predictable power.
• Modular composite chassis designed for serviceability and impact resistance.
• Body-post free design eliminates traditional body posts and clips for a cleaner look and faster body changes.
• Full-time shaft-driven 4-wheel drive for consistent traction and durability.
• All-metal gears and CVDs throughout the driveline for long life under big loads.
• Torque-Biasing Center Drive absorbs impacts and distributes power for controlled traction.
• 24 mm splined wheel hexes retained with a clip for secure wheels and easy maintenance.
• 17 mm hex on wheel outside for common wheel fitment.
• Sealed silicone fluid-filled differentials with large-module ring and pinion gears for consistent gear engagement.
• Splined outdrives attached with thru-bolt for positive engagement and easy service.
• Cush Drive with steel spur gear for shock absorption and drivetrain longevity.
• Fully machined aluminum stub axles for precise wheel mounting.
• Splined aluminum center driveshaft for long-term durability.
• Precision, preset gear mesh — no manual gear mesh adjustment required, and motor retention is separate from gear mesh.
• Interlocking front and rear bulkheads and a motor mount to the rear bulkhead to reduce gear-crunching flex.
• Driveline sealed in the chassis to keep out dirt and grit for longer service intervals.
• Pivoting battery hold-downs adjustable for different battery sizes and more secure than conventional systems; integrated into the chassis brace for increased stiffness.
• Front energy-absorbing rubber bumper and lower front/rear skids for impact and abrasion resistance.
• High-strength glue and bead construction for reliable tire-to-wheel bonding.
• Integrated nerf bars to protect against side impacts.
• High-output steering servo (2085 digital, high-torque, waterproof) wired into the RX box with internal routing to keep the chassis tidy.
• Reinforced servo mounting — double-shear, bearing-supported servo horn and a new case support mounting system.
• Suspension engineered for travel and steering with double-shear strength at critical points and high-strength steel suspension pins that resist backing out.
• 4 mm machined pivot balls and C-hub/steering block geometry that maximize steering angle and allow adjustable roll center.
• Fixed, high-strength camber and toe links with steel upper and lower tie bars for consistent geometry under load.
• Full-contact sealed bearings used in exposed locations for reduced wear.
• Machined aluminum threaded shock bodies with extra-large bore and capacity, 5.2 mm damper shafts, lower seal cartridges with integrated wipers, adjustable upper spring retainers, plastic shock caps with pivot balls, fixed shock locations, and bolted lower spring perches.
• 8x4x4 inch all-terrain tires on large, dual-diameter wheels with a specifically formulated 8S rubber compound and 2-piece foam inserts for consistent handling.
