Cross RC EMO XX Stegosaurus 1/6 775 Brushed 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 conveys 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 using thick steel plates formed by hundred-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.
• The front and rear axle structures use reverse transmission, with 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 predictable handling 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 windup.
• The axle shafts in the housings and the output shafts at the wheel hubs are made of reinforced steel. The axle shafts have a 6 mm diameter, while the wheel-hub output shafts have an 8 mm diameter 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 control rod, and four rear links plus a sway bar, with link diameters of up to 10 mm for a thick, powerful design. This gives the suspension excellent flexibility when twisting and high lateral impact resistance. The upper pivot of the front lateral control rod has also been upgraded with a steel module.
• Shock absorbers with a large 26 mm diameter, precision-machined from high-quality aluminum alloy using CNC technology. Adjustable preload and up to 40 mm of maximum travel provide strong support for the entire vehicle while making it easy to achieve agile handling.
• Strong ball joints made with special materials: large ball-joint cups and fine steel ball-joint beads 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 with parallel output, delivering strong power 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 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 to reduce gear wear and extend service life.

Brain: precise control × intelligent protection

• High-voltage servos throughout the vehicle: 5-car-class 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 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 servo from burning out due to an incorrect operating stroke.
• Dragon Claws: Equipped with newly developed ROCK BREAKER “Rock Roar” MT tires, which use large, multi-edged vertical tread claws to firmly grip any rock face. MARSH RANGER “Marsh Roam” MT tires have also been launched, featuring a classic herringbone tread pattern that easily traverses muddy terrain. The vehicle comes equipped with nylon beadlock wheels, using screw nuts to clamp the tires securely so you can drive freely without worrying about the tires coming loose.
• Armor: Thickened PC material with the car’s inner shell and an internal composite roll cage, realistic appearance details, and protection for the vehicle body against damage. Firmly connected to the chassis via a four-point quick-release structure, with a realistic appearance and easy disassembly for 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 rock crawlers and many other models, larger than the mass-produced RTR rock crawlers currently available worldwide.
• Dragon Spine: On the third axle of the EMO XXL 6x6 Thunder Dragon, using a bridge-type transmission axle structure. The bridge shaft structure is extremely 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.
