It all began in 1998 when Aaron Harris, a world-renowned mechanical design engineer, machinist, and design visionary founded Hardcore Racing Components. The company
quickly became the leading manufacturer of upgrade components for RC cars, known for innovations such as the first-ever titanium performance chassis. Hardcore Racing
Components catered to both premier off-road and on-road RC car platforms and built an extensive line of innovative billet-machined components that dominated the RC car hopup aftermarket from 1998 to 2005.

In 2023, Mr. Harris chose to re-enter the RC car upgrade market under the RCx brand name, a division of his main design and engineering company, Vast Dynamic Innovation LLC. The Vast RCx brand is dedicated to designing and manufacturing complete lines of
components. We utilize unique materials, innovative manufacturing processes, and distinctive designs. All parts and components are entirely crafted by Mr. Harris and are proudly manufactured 100% in the USA, under his complete control and supervision.

At VAST-RCX, our mission is to redefine the standard of performance and reliability in the radio-controlled (RC) vehicle industry by delivering premium-grade products engineered for serious
hobbyists, builders, and competitive drivers. We exist to serve a growing global community of RC enthusiasts who demand more than just parts — they demand precision, innovation, and trust.


We are driven by three core principles:

Engineering Without Compromise
Every VAST-RCX product is designed with purpose — combining rugged durability, cutting-edge materials, and real-world performance testing. From hardcore off-roaders to scale-detail showpieces, we ensure our components meet the highest standards of functionality and fitment, right out of the box.


Supporting the RC Journey
We believe in empowering our customers at every stage of their RC journey — from first build to final race lap. Our commitment goes beyond the sale, offering comprehensive technical support, upgrade paths, and a platform where builders can connect, learn, and evolve.


Cultivating a Global RC Community
We’re not just a company — we’re part of a movement. VAST-RCX proudly supports a passionate and
diverse community of creators, competitors, and innovators. We listen closely to customer feedback,
collaborate with builders and influencers, and continually adapt to the changing landscape of the
hobby.


At VAST-RCX, we don’t just build parts — we build possibilities. Whether you're crawling over rocks, tearing through trails, or refining the perfect scale rig, we’re here to make sure every moment behind the wheel reflects the performance and precision you expect.
