This new car would have all the same benefits of a hobby-class kit such as replaceable parts, hop-ups, and a high-quality component radio system, however it would be fully assembled with a colorful body, right out of the box. Traxxas coined the term "Ready-To-Run" (RTR) to describe this new class. At first, acceptance of the RTR concept was slow because traditional R/C kits had always been unassembled. Once people realized that a Traxxas RTR had the same performance and quality as the traditional R/C kits, only that they didn't have to build it, the ready-to-run car was a runaway hit A kit version would still be offered for those who still wanted to have the building experience.
