Engineering Without Borders: A Legacy of Global Cooperation
The legend of the HongYan HY6 (CQ261) is not written in conflict, but in the enduring ink of international cooperation. Its story is one of the most profound industrial odysseys of the 20th century.
In 1964, against a backdrop of a divided world, a historic bridge was built between East and West. Through a landmark $14.6 million technology transfer agreement, the legendary French heavy-truck pioneer Berliet joined forces with Chinese visionaries. This was more than a commercial deal; it was the spark that ignited a modern industrial revolution deep in the misty valleys of Yibin.
There, a former high-voltage appliance factory was transformed into a cradle of automotive excellence. It was a crucible where French engineering precision met Chinese resilience. Engineers from both nations overcame immense challenges—painstakingly auditing thousands of technical blueprints and bridging vast cultural divides—to evolve the Berliet GBU15 into the CQ261.
For decades, this "Iron Spine" shouldered the weight of a developing nation. From towing heavy artillery through the rugged, rain-slicked mountains of the southern frontier to hauling the raw materials that built modern cities, the CQ261 became a cultural icon of reliability. It proved that a "correct tool," crafted with uncompromising standards, transcends its military origins to become a universal symbol of heavy-duty capability.
Today, the HY6 stands as a 1/10 scale tribute to that golden age of mechanical purity. It is not just a model; it is a revival of that spirit of international industrialism—a masterpiece of history, now ready for your command.
The Ultimate Industrial 6x6: Core Market Advantages
The HY6 is not merely a model; it is a heavy-duty industrial machine scaled down for the trail. Its foundation is built upon 6mm thick CNC-machined aluminum chassis rails, providing a level of structural rigidity rarely seen in the RC world. This uncompromising use of metal extends to the rear, where a solid, seamless 6mm aluminum cargo bed floor ensures that the vehicle can handle varying heavy loads without deformation.
To manage this weight while maintaining stability, the engineering team designed a unique recessed battery compartment. By sinking the power source deep into the chassis, the center of gravity is drastically lowered, allowing this 800mm-long giant to negotiate steep side-hills with the stability of a much smaller crawler. The suspension system honors its heritage with a leaf-spring architecture that replicates the authentic load-bearing physics of the original truck, though it remains fully compatible with oil-filled shock upgrades for those seeking extreme articulation.
Precision Power and The "Dual-Drive" Revolution
Under the hood, the HY6 introduces a groundbreaking drivetrain designed for longevity and realism. It features an industry-first Dual-Drive Transmission system for the middle and rear axles. By splitting the power distribution, this design not only mimics the complex mechanics of the full-scale truck but also reduces stress on individual components, extending the drivetrain's lifespan by over 30% compared to traditional single-shaft setups.
Control is absolute. The front axle is equipped with a remote-locking differential, allowing the driver to switch instantly between open-diff maneuverability for tight turns and locked-diff traction for escaping mud or rocks. This is paired with a dual-speed gearbox operated by a dedicated servo, featuring a "visible shifting" structure that allows for easy mechanical inspection.
The HongYan HY6 is not just a vehicle; it is a mechanical symbiosis of past and future, a tool of precision designed to conquer the most demanding terrain while honoring a global legacy of engineering. The expedition begins now.

I need one when is in stock
anyone know the price of this, this is a must have … holy. the history alone behind this truck makes it legendary well done
Beautiful addition to the fleet! Looks really amazing. Rlaarlo is really evolving into a top notch RC company. Excellent quality throughout and wonderful attention to detail. I will for sure want to put one of these into my stable.
Ahora que estoy pensando en volver con la actividad en mi canal de Youtube, este sería el vehículo perfecto para el retorno por todo lo alto. Estoy deseando que salga a la venta y añadido a mi colección. Estaba pensando en comprar un mk07 pero habiendo descubierto esta nueva máquina creo que voy a esperar. Seguir así, el mundo rc necesita este nuevo enfoque de super escalas.
This RC is gonna be crazy useful and I hope to get soon it’s arrived in the shopping
