Kyosho 34303 ULTIMA RB7 racing chassis overview

The Kyosho 34303 ULTIMA RB7 1/10 EP 2WD Buggy Kit continues the RB lineage with refinements aimed at modern indoor circuits. Drawing on the RB6 heritage, the RB7 is tailored for high-grip carpet and artificial turf, focusing on low-slung balance and predictable control for race settings.

Chassis and handling upgrades

The RB7 adopts a shortened wheelbase and a lighter chassis plate to boost rigidity and steering response. Aerodynamic bodywork and a high-downforce rear wing combine with revised suspension arms and steering knuckles to improve cornering precision and high-speed stability.

Race-ready mechanical features

Notable elements include a short Li-Po battery layout, tungsten balls in the ball differential for smoother engagement, and a generous slipper clutch for high-power setups. The hexagonal wheel hub clamp provides solid wheel retention, while the center mount revisions help distribute chassis loads more evenly.

Tuning and upgrade potential

The platform supports a wide selection of optional parts and gearbox choices to match track conditions. From suspension geometry tweaks to gearbox settings, builders can tune the RB7 to suit driving style and specific circuit grip levels.

Whether preparing for club races or refining setup for regional events, the Kyosho 34303 ULTIMA RB7 gives experienced drivers a versatile, competition-oriented base to optimise handling and grip.
