Overview

Off-road buggies are famous for their ‘go-anywhere’ capabilities and the 1/10 scale electric powered format is particularly popular. True to its dirt bashing prowess, Kyosho is proud to introduce the ‘Dune Master’ to the Ultima SB series of mid-class electric buggies. Built on the Ultima SB chassis with rear motor RWD (rear wheel drive) for its superior rear tire traction and maneuvrability, the Dune Master features a new basher body that looks like a modified car rather than the open wheel buggy style. New tire and wheel designs highlight the appeal of the original car body style. Based on the Ultima RB5 chassis which was previously a competition-level racer, each component has been reviewed to deliver superior handling and control for beginners at an optimal price. The rear motor configuration improves rear grip, allowing for traction stability on low-grip surfaces such as sports fields and open terrain as well as delivering high-speed performance on proper R/C race tracks. The new Ultima SB Dune Master and its highly popular Ultima SB Dirt Master predecessor, set the standard for modern mid-class buggies that can be enjoyed by all drivers, either as a step up from entry-level models, or as a second car for experienced drivers.
