Cross RC EMO XX Stegosaurus 1/6 Brushless Truck Crawler PNP

Overview

The EMO XX Stegosaurus is a 1/6-scale crawler measuring over 80 cm long 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 limits of “large-scale crawling” and delivering 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 from 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 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 at high speed.
• Combined with an increased input-shaft angle and a special mounting-point angle, the smooth transmission effectively minimizes axle wind-up.
• The axle shafts inside the axles 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 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 a lateral pressure rod, and four rear links plus a sway bar, with link diameters of up to 10 mm for a thick and powerful design. This gives the suspension excellent flexibility when twisting through turns, while also providing high lateral impact resistance. The upper pivot point of the front lateral pressure rod has been further reinforced with a steel module.
• Shock absorbers with a large 26 mm diameter, made from high-quality aluminum alloy using high-precision CNC machining. Adjustable preload and a maximum travel of 40 mm provide excellent support for the entire vehicle while making it easy to achieve an agile stance.
• Strong ball joints made from special materials, featuring large ball-joint cups and fine steel ball-joint balls 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 parallel, delivering powerful output and a continuous supply of limitless 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 to reduce gear wear and extend service life.

Brain: precise control × intelligent protection

• High-voltage servos throughout the vehicle: 1 × 70 kg high-power, 5-car-grade high-voltage steering servo + 3 × 25 kg standard high-voltage servos.
• Power distribution: The 70 kg high-power steering servo is powered by an independent ESC BEC, avoiding the impact of servo power-load fluctuations 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 and protecting 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 servos 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 vehicle comes equipped with nylon clamp 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. 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, with a rear cargo area measuring 693 mm by 325 mm, making it easy to transport long-wheelbase 1/8-scale crawler cars and many models, larger than the world's existing mass-produced RTR crawler cars.
• Dragon Spine: On the third axle of the EMO XXL 6x6 Thunder Dragon, using a bridge-style transmission axle structure. The bridge-shaft structure is extremely strong and resistant to high torque, allowing the second and third axles to reliably transfer thousands of kilograms of force under extreme cross-axle conditions, making it easy to crush cliffs.
