World Champion Drifter Vaughn Gittin Jr. and the Need for Speed crew teamed up to build the one-of-a-kind, fully-functional Street, Track and Drift machine RTR-X, and this is the official, authorized RC replica, only from HPI! Balancing 5.0 litres of tyre-shredding American horsepower with vintage American, Japanese, European and Drift culture inspired design influences, Vaughn incorporated state-of-the-art technology while retaining a nostalgic feel into his vision for the 1969 Ford Mustang's timeless body. The RTR-X was designed and built from the ground up to be driven hard — the RTR-X is NOT a trailer queen. The RS4 Sport 3 is a fun, easy-to-drive and simple-to-maintain street car featuring a completely pre-assembled race car chassis. Packed with 2.4GHz control and complete waterproof protection, the chassis is factory assembled right out of the box, making it a quick and easy way to get straight into driving, racing and honing your skills.
