Cross RC EMO XXL Thunder Dragon 1/6 Brushless Truck Crawler PNP

Overview

The EMO XX Stegosaurus is a 1/6-scale 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 ferocity of a prehistoric beast, redefining the boundaries of “large-scale climbing” and delivering an impressive presence on any terrain.

Skeleton: Steel Beams × Imported Nylon

• Reinforced chassis made from thick steel plates formed by one-hundred-ton stamping to create a realistic frame.
• The axles, crossmembers, and various connecting parts 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 steering-position positive Ackermann angle of 5 degrees, 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 torque effects.
• The axle shafts in the bridge and the output shafts at the outer ends are made of reinforced steel. The axle shafts have a diameter of 6 mm, while the outer output shafts have a diameter of 8 mm and are fitted with 17 mm connectors, making them strong and impact-resistant.

Axles: Lightweight Aluminum CNC × Reinforced Ball Joints

• Suspension using three front links plus lateral pressure rods, and four rear links plus a stabilizer bar. The links have a diameter of up to 10 mm and are thick and strong. This gives the suspension great flexibility when twisting through turns, while also providing high lateral impact resistance. The upper pivot of the front lateral pressure rod has been further reinforced with a steel module.
• Shock absorbers with a large 26 mm diameter, manufactured from high-quality aluminum alloy using high-precision CNC machining. Adjustable preload and up to 40 mm of maximum travel provide strong support for the entire vehicle while making it easy to achieve an agile stance.
• Strong ball joints made with specially selected materials: large ball-joint cups paired with fine steel ball-joint beads, combining rigidity and flexibility for 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 with parallel output, delivering powerful performance and continuously supplying 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 fully 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 70KG high-power steering servo *1 + high-voltage 25KG 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 precise vehicle 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 servo-travel control, intelligently protecting the servo from burning out due to incorrect operating travel.
• 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 are also available, featuring a classic herringbone tread that easily navigates muddy terrain. The vehicle comes 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: Solid PC material with an inner vehicle shell and an internal composite roll cage, realistic appearance details, and protection for the vehicle body against damage. Firmly connected to the chassis by a four-point quick-release structure, with a realistic appearance, easy disassembly, and reliable performance.
• 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, and can easily transport long-wheelbase 1/8-scale crawlers and many other models, making it larger than the mass-produced RTR crawlers currently available worldwide.
• Dragon Spine: On the third axle of the EMO XXL 6x6 Thunder Dragon, a bridge-style transmission axle structure is used. The bridge axle structure is exceptionally strong and can withstand high torque, allowing the second and third axles to reliably transmit thousands of kilograms of force under extreme cross-axle conditions, making it easy to crush cliffs.
