Cross RC EMO XXL Thunder Dragon 1/6 775 Brushed Truck Crawler PNP

Overview

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

Frame: Steel Beams × Imported Nylon

• Reinforced chassis using thick steel plates formed by 100-ton stamping to create a realistic frame.
• The axles, crossmembers, and various connecting parts are made of imported nylon with a special formula, 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 stress.
• The half-shafts in the axles and the output shafts at the wheel ends are made of reinforced steel. The half-shafts have a diameter of 6 mm, while the wheel-end output shafts have a diameter of 8 mm and are equipped with a 17 mm connector, making them strong and impact-resistant.

Axles: Lightweight Aluminum CNC × Reinforced Ball Joints

• Suspension using three front links plus lateral track rods, and four rear links plus a sway bar, with link diameters of up to 10 mm—thick and powerful. This gives the suspension great flexibility when twisting the chassis while also providing high lateral impact resistance. The upper pivot of the front lateral track rod has been further reinforced with a steel module.
• Shock absorbers with a large 26 mm diameter, precision-machined from high-quality aluminum alloy using CNC processing. Adjustable preload and up to 40 mm of maximum travel provide good support for the entire vehicle while allowing it to move with agility.
• Strong ball joints made with special materials, featuring large ball-joint sockets and fine steel ball-joint beads that combine 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 in a parallel-output configuration, delivering powerful performance and a continuous supply of endless 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 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: one 70 kg high-voltage, high-power steering servo rated for 5-car scale, plus three 25 kg high-voltage standard servos.
• Power distribution: The 70 kg high-torque 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 burnout.
• Functional servo full-travel adjustment: CROSSRC’s proprietary front and rear differential locks and gearbox controls use servo full-travel control, intelligently protecting the servos from burning out due to incorrect travel settings.
• 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, with a classic herringbone tread that easily handles 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 them 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 via a four-point quick-release structure, with 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 area measuring 693 mm by 325 mm, making it easy to transport long-wheelbase 1/8-scale rock crawlers and many other models. It is 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-like transmission shaft structure is used. The bridge-shaft structure is exceptionally strong and can withstand high torque, enabling the second and third axles to reliably transmit thousands of kilograms of force under extreme cross-axle conditions, easily crushing cliffs.
