What the Kyosho 34303 ULTIMA RB7 brings to the track

The Kyosho 34303 ULTIMA RB7 1/10 EP 2WD Buggy Kit is an evolution of the RB series designed to meet the demands of modern high-traction racing. It builds on proven low-down midship concepts to deliver controlled handling on carpet and artificial turf circuits.

Key design refinements

Engineered with a shortened wheelbase and a refined, lighter chassis, the RB7 improves rigidity and response. Its aerodynamic shell and strong rear wing pair with revised suspension and steering components to help maintain stability through fast corners.

Components aimed at race reliability

The RB7 includes a short Li-Po battery footprint, tungsten balls in the ball differential for consistent operation, and a large slipper clutch to manage high torque inputs. Precision clamp hex hubs and an updated center mount add to predictable behaviour under load.

Setup scope and upgrade choices

There is a broad range of optional parts and gearbox choices to tailor the car to different track surfaces and driving styles. From suspension parts to gear options, you can build a setup that matches your racing plan.

The Kyosho 34303 ULTIMA RB7 is well suited to competitive drivers and experienced hobbyists who want a responsive, adjustable platform for high-traction racing.

Yes. Matching tyre compound and tread to the circuit surface is important. Use tyres made for carpet or high-grip turf to exploit the RB7s stability and steering precision.
The tungsten ball-equipped ball differential offers durable, consistent engagement. Adjusting diff preload and grease levels changes corner entry and traction transfer to suit driver preference.
After a session inspect suspension pivots, check differential and slipper wear, clean bearings, and recheck screw torque. Small adjustments to camber and toe may be needed as tyres bed in.
Begin with a medium spring rate, modest rear toe, and slight front negative camber. Use the short battery position and keep ride height low to maintain the RB7s designed balance on carpet tracks.
