Cross RC EMO XX Stegosaurus 1/6 Truck Crawler Kit

Overview

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

Skeleton: Steel Frame × Imported Nylon

• Reinforced chassis using thick steel plates formed by one-hundred-ton stamping to create a realistic frame.
• The axles, crossmembers, and various connecting parts are made from imported nylon with a special formula, achieving an excellent 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 easier-to-follow 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 housings and the output shafts at the wheel ends are made of reinforced steel. The axle shafts have a diameter of 6 mm, while the wheel-end output shafts measure 8 mm and feature a 17 mm connector, delivering excellent strength and impact resistance.

Axles: Lightweight Aluminum CNC × Reinforced Ball Joints

• Suspension featuring three front links plus a lateral torque rod, and four rear links plus a sway bar. With link diameters of up to 10 mm, it is 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 torque 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 travel provide excellent support for the entire vehicle while effortlessly showcasing an agile stance.
• Strong ball joints made from special 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, delivering powerful output and continuously supplying boundless 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 play after adding power) and an ARTR version without electronics (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-torque 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 operation. It also features servo stall protection, automatically reducing power output when the servo is stalled for an extended period to protect it from burning out.
• Functional servo full-travel adjustment: CROSSRC’s original front and rear differential locks and gearbox controls use servo full-travel control, intelligently protecting the servo from burning out due to an incorrect operating range.
• Dragon Claws: Equipped with newly developed ROCK BREAKER “Rock Roar” MT tires, featuring large, multi-edged vertical tread claws that 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, using screw nuts to secure the tires so you can drive freely without worrying about the tires coming loose.
• Armor: Thick PC material with an inner car shell and internal composite roll cage, realistic exterior details, and protection of the car body from damage. Closely connected to the chassis by a four-point quick-release structure, with a realistic appearance and easy, reliable disassembly.
• Cang Armor Carrying Mountain: The EMO XXL 6x6 Thunder Dragon has a vehicle length of 1.06 meters, a rear cargo area measuring 693 mm by 325 mm, making it easy to transport 1/8-scale long-wheelbase rock crawlers and many other models, larger than the existing mass-produced RTR rock crawlers worldwide.
• Dragon Spine: On the third axle of the EMO XXL 6x6 Thunder Dragon, a bridge-type transmission axle structure is used. The bridge axle structure is extremely strong and resistant to high torque, enabling the second and third axles to reliably transmit thousands of kilograms of force under extreme cross-axle conditions, making it easy to crush cliffs.
