CROSSRC EMO XL Big Bison 1/8 Scale 6x6 RC Crawler Truck
The CROSSRC EMO XL Big Bison is a 1/8 scale 6x6 RC crawler designed for off-road trail driving and controlled climbing. Its six-wheel-drive layout combines portal axles, front and rear differential locks, a two-speed metal gearbox and a multi-link suspension. The third axle uses an aluminum and fiber-composite suspension mount, while the wide modular tailgate provides space for scale accessories and customization.
Choose the 775 brushed or HobbyWing brushless version. The CROSSRC EMO XL Big Bison is available in Blue, Red, Yellow and Gray. Battery and charger inclusion depends on the Battery+Chargers option selected on the product page.
Key Features:
Six-Wheel Drive with Controllable Differential Locks
The CROSSRC EMO XL Big Bison uses a 6x6 portal-axle drivetrain. The front and rear differential locks are controlled separately, while the two rear axles lock together. This arrangement lets the driver select the available differential-lock configuration for the terrain.
Two-Speed All-Metal Gearbox
The two-speed transmission provides a lower gear for controlled crawling and a higher gear for faster trail driving. The gearbox uses a combination of machined and MIM gears. A CNC aluminum motor mount helps dissipate motor heat.
Reinforced Third-Axle Suspension
The third-axle suspension mount combines aluminum and fiber composite for a balance of strength and low weight. The rear balance-linkage system is designed for the three-axle chassis, and reinforced frame rails support the vehicle’s off-road drivetrain.
Multi-Link Suspension and CNC Shocks
The suspension uses 7 mm diameter 304 stainless-steel links with reinforced ball ends. The 21 mm CNC shocks have vacuum-plated shafts and are supplied with 350CST shock oil. The rear linkage geometry supports roll-center control while allowing the shocks to move through their suspension travel.
All-Terrain Tires and Portal Axles
The CROSSRC EMO XL Big Bison uses high-performance AT tires with a tread pattern designed for traction across off-road surfaces. Its portal-axle housings use weather-resistant nylon with metal internal gears.
Remote-Controlled Lighting and Sound Effects
The vehicle includes a high-power lighting system with grille warning lights and multiple modes controlled from the transmitter. The product specifications also list controllable sound effects such as a horn, alarm and music.

Enhanced transmission concept specially developed for six-wheel drive:
CROSSRC EMO XL uses an over-bridge transmission shaft and a double reverse transmission portal bridge structure as the driving basis. It is equipped with front and rear individually controlled differential locks (rear dual axles are controlled simultaneously) and a two-speed high-strength all-metal wheel gearbox to meet the current popular high-power high-speed climbing gameplay.
The CROSSRC EMO XL third axle suspension is fixed with a combination of aircraft aluminum and fiber, which is both strong and lightweight. The impact resistance of the last axle suspension in the event of an accidental squatting is enhanced during the steep slope process, greatly improving the reliability of the entire vehicle.
Stable and reliable basic platform:
The Crossrc 1/8 EMO platform has experienced three generations of evolution, has been continuously strengthened and upgraded, and is widely respected around the world. It provides reliable and high-performance guarantee for the new car CROSSRC EMO XL.
The metal gear reverse transmission gearbox uses aviation aluminum CNC motor base to effectively help the motor dissipate heat; the internal gears are machined and mixed with MIM injection technology gears to achieve high strength, wear resistance and low noise.
The motor has been newly upgraded, and the motor versions include 775 brushed version and HobbyWing brushless version to choose from!
The Hobbywing 8IGHT FOC Brushless RTR is built for serious performance, powered by a custom 1/8-scale FOC brushless system with a 1800KV motor and 4S LiPo support. Rip through the track with explosive speed, or dial it back for smooth, precise control when you need finesse—this rig delivers it all. (Optional)
The suspension tie rods are made of 7mm diameter 304 stainless steel tie rods, which are wear-resistant and rust-proof, and also have the effect of lowering the center of gravity; the suspension tie rod ball head buckles are upgraded to enlarged reinforced ball head buckles, which are more durable and impact resistant.
The ultra-large diameter 21mm CNC shock absorber uses vacuum electroplated shock absorber rods to improve the smoothness of the shock absorber and better utilize the damping oil, providing strong support and flexible posture performance. The factory has been filled with 350CST shock absorber oil and Complete the drain assembly.
The heavy-duty reinforced girder increases the cross-section ratio by 200% and increases the strength multiplier, making it suitable for high-speed violent gameplay with high-power modifications and is not easily damaged.
The strong front and rear door axles are made of imported high-performance weather-resistant nylon to meet the strength needs of friends in areas with a cold temperature of -20 degrees Celsius.
The second generation rear balance link system updates the geometric data again according to the new structure. The CROSSRC EMOX Big Rhino, the first in the model industry in 2022, effectively improves the control of the rolling center of gravity during high-speed control without affecting the work of the shock absorber, making it smooth and non-stuck.
Big Tiger's same VELOCIRAPTOR high-performance AT tire, with targeted tread patterns that maximize road-holding performance.
The original car is equipped with a high-power light set, including a central grid warning light, with multiple modes and remote control.
The entire vehicle adopts 7.4V high-voltage circuit, full-rudder gear shifting and differential lock control mechanism, Hobbywing customized version 4S 880 ESC, and linear high-power 560 carbon brush motor. Riders who subsequently upgrade to advanced servos and remote controls do not need to worry about power supply and differential speed settings. It is simple and convenient.
