RC10 ‘89 Stealth Car Masami Edition Kit, ASC-6043

Team Associated RC10 ‘89 Stealth Car Masami Edition Kit, ASC-6043 At the 1989 IFMAR 1/10 Off-Road World Championships in St. Ives, Australia, Masami Hirosaka drove the groundbreaking RC10 “Stealth” car to victory. This prototype from Team Associated featured a revolutionary Stealth® 3-gear transmission, offering smoother and more efficient power delivery compared to the standard 6-gear setup. Built around a lightweight chassis and equipped with a specially tuned Reedy motor, Masami’s RC10 combined cutting-edge technology with his signature smooth, aggressive driving style. Masami’s win in Australia didn’t just earn him another world title — it changed RC racing forever. The success of the Stealth RC10 set a new standard for off-road design, and the Stealth transmission would later become the foundation for future Team Associated vehicles. Hirosaka’s performance, driving a car most competitors hadn’t even seen before, remains one of the most iconic moments in RC history. The 1989 Team Associated Stealth Car prototype was a radical evolution of the RC10 platform, purpose-built for top-tier competition at the IFMAR World Championships in Sydney, Australia. Designed in secrecy, it featured a number of innovative elements that set a new benchmark in 2WD off-road buggy performance. Most notably, it introduced the Stealth transmission—a compact, three-gear unit with internal slipper clutch. Unlike the bulkier six-gear design of the original RC10, the Stealth transmission offered smoother, more efficient power transfer and a lower center of gravity. The prototype also utilized a narrowed and milled aluminum chassis for reduced weight and improved agility. The front end was modified with new geometry for better steering response, while the rear featured longer suspension arms and revised shock positioning to improve traction and stability. Lightweight materials such as carbon fiber and titanium were used extensively, showcasing a design philosophy that prioritized speed, balance, and durability. The Stealth Car had a lower profile body and sleek, streamlined aesthetics that matched its high-performance internals. Though never sold as a complete kit, the design innovations of the 1989 Stealth Car directly influenced future Associated models and reshaped competitive RC buggy engineering for years to come.
