Cross RC EMO XX Stegosaurus 1/6 Brushless Crawler PNP

Overview

The EMO XX Stegosaurus is a 1/6-scale rock crawler measuring over 80 cm in length and weighing 13 kg, combining immense power with agility. With a flexible body and dynamic movements, every angle radiates the wildness of a prehistoric beast, redefining the boundaries of “large-scale climbing” and delivering an impressive presence on any terrain.

Frame: Steel Beams × Imported Nylon

• Reinforced chassis made from thick steel plates formed by 100-ton stamping to create a realistic frame.
• The axles, crossmembers, and various connecting components are made of imported nylon with a special formulation, achieving a good balance between chassis strength and toughness.
• Front and rear axle structures with reverse transmission, a maximum positive Ackermann angle of 5 degrees at full steering lock, an 8-degree steering-knuckle inclination, and a maximum caster angle of 8 degrees. This provides better tracking after the steering returns to center, resulting in more stable and predictable driving characteristics when crossing terrain at high speed.
• Combined with an increased input-shaft angle and a special mounting-point angle, the smooth transmission effectively minimizes axle stress.
• The axle shafts inside the axles and the output shafts at the wheel ends are made of reinforced steel. The axle shafts have a 6 mm diameter, while the wheel-end output shafts have an 8 mm diameter and are fitted with a 17 mm connector, making them strong and impact-resistant.

Axles: Lightweight Aluminum CNC × Reinforced Ball Joints

• Suspension featuring three front links plus lateral tie rods, four rear links plus a sway bar, and links up to 10 mm in diameter—thick and powerful. This gives the suspension great flexibility when twisting through turns, while also providing high lateral impact resistance. The upper pivot of the front lateral tie rod has been further reinforced with a steel module.
• Shock absorbers with a large 26 mm diameter, precision CNC-machined from high-quality aluminum alloy. Adjustable preload and up to 40 mm of maximum travel provide excellent support for the entire vehicle while allowing it to move with agility.
• Strong ball joints made from specialized materials, combining large ball-joint cups with fine steel ball-joint beads for a balance of rigidity and flexibility, agility, and impact resistance.

Drakenhart: Dual Power × Fine Steel Internal Teeth

• Powerful performance: the brushed RTR version is equipped with two custom 775 high-power motors in parallel for powerful output, continuously delivering unlimited energy through dual high-voltage 880 ESCs. The large front battery compartment, measuring 160 mm × 85 mm × 55 mm, accommodates two 8000 mAh 3S batteries. The first model is available in a dual-775 RTR version (ready to run after adding power) and an ARTR version without power (chassis pre-installed). The brushless version will be launched soon.
• The high-torque two-speed gearbox uses all-metal gears. The heavy-load end features integrated steel gears to ensure high strength, while the transmission end uses self-lubricating aluminum gears, reducing gear wear and extending service life.

Brains: precise control × intelligent protection

• High-voltage servos throughout the vehicle: 5-car-level high-voltage 70 kg high-power steering servo *1 + high-voltage 25 kg standard servos *3.
• Power distribution: the 70 kg high-power steering servo is powered by an independent ESC BEC, avoiding the impact of servo power loads on the vehicle’s precise steering and turn-signal group operation. It also features servo stall protection, automatically reducing power output when the servo remains stalled for an extended period, protecting it from burning out.
• Functional servo full-travel adjustment: CROSSRC’s original front and rear differential locks and gearbox controls use full-travel servo control, intelligently protecting the servos from burning out due to incorrect operating travel.
• Dragon Claws: Equipped with newly developed ROCK BREAKER “Rock Roar” MT tires, which use large, multi-edged vertical tire claws to firmly grip every rock face. MARSH RANGER “Marsh Roam” MT tires have also been launched, featuring a classic herringbone tread that easily traverses muddy terrain. The original vehicle is equipped with nylon beadlock wheels that use screw nuts to secure the tires, allowing you to drive freely without worrying about the tires coming loose.
• Armor: thickened PC material with an inner car shell and an internal composite roll cage, realistic exterior details, and protection for the car body against damage. Firmly connected to the chassis with a four-point quick-release structure, featuring a realistic appearance and easy, reliable disassembly.
• Cang Armor Carrying Mountain: The EMO XXL 6x6 Thunder Dragon is 1.06 meters long, with a rear cargo compartment measuring 693 mm by 325 mm, making it easy to transport long-wheelbase 1/8-scale crawler cars and many models, larger than the mass-produced RTR crawler cars currently available worldwide.
• Dragon Spine: On the third axle of the EMO XXL 6x6 Thunder Dragon, a bridge-type transmission axle structure is used. The bridge-shaft structure is exceptionally strong and resistant to high torque, enabling the second and third axles to reliably transfer thousands of kilograms of force under extreme cross-axle conditions, making it easy to crush cliffs.
