Optimized version of RTA. This kit contains all the V1.2 parts, the new V2 front end, as well as the essential options in order to make a chassis “ready to win” as soon as it is assembled. The objective of this new version was to make a better quality kit, easier to assemble and setup. We have therefore completely redesigned the rear suspension in order to increase rear traction while simplifying its adjustment. In order to make a “ready to run” chassis, the kit is now equipped with a dual spring shock absorber and a ball differential. All the parts of this RTA V1.2 are adaptable on the RTA V1 and vice versa.
