The drift world champion Vaughn Gittin Jr. and Mustang RTR have teamed up with Need for Speed to create this unique street, track, and drift machine. It features 5.0 liters of tire-shredding American power, inspired by design influences from American, Japanese, and European drift culture. Vaughn has combined cutting-edge technology with the nostalgic, timeless design of a '69 Ford Mustang. The RTR-X has been built from the ground up for the toughest challenges; it is not a model to be handled with kid gloves. While Vaughn is the only one drifting his Mustang on the streets, the whole world can enjoy driving the HPI 1:10 RTR-X. The RTR HPI RS4 SPORT 3 promises a lot of fun, offers excellent handling, and is low maintenance. It is now waterproof and equipped with a 2.4 GHz radio control system. The chassis comes professionally pre-assembled and is ready to drive straight out of the box. With the HPI RS4 SPORT 3, you can quickly and easily experience professional RC car racing. Maximum fun.
