Introducing the Kyosho 34303 ULTIMA RB7 race buggy

The Kyosho 34303 ULTIMA RB7 1/10 EP 2WD Buggy Kit carries forward the proven RB concept with updates aimed at modern indoor and high-traction outdoor racing. Its layout and component choices prioritise low center of gravity and stable traction for fast, clean laps.

Structural improvements for track work

A shortened wheelbase paired with a lightweight yet stiff chassis improves turn-in and mid-corner consistency. Aerodynamic bodywork and a high-downforce wing work alongside reworked suspension arms and steering knuckles to enhance composure at speed.

Performance components and drivetrain

The RB7 features a short Li-Po battery format, tungsten-bearing ball differential for longevity, and a high-capacity slipper clutch to tame powerful motors. Clamp-type hex hubs and a revised center mount contribute to precise wheel control and chassis stiffness.

Tuning pathways and upgrades

Drivers can tailor the RB7 via gearbox options and a long list of hop-ups to match specific track conditions. Suspension, gear ratios, and accessory parts let racers fine-tune handling and durability.

From club nights to competitive events, the Kyosho 34303 ULTIMA RB7 is a capable and configurable platform for drivers focused on lap time and handling balance.

What electronic components do I need to complete this kit?

You will need a compatible brushless motor and esc, a short Li-Po battery, a digital servo for steering, and a 2.4GHz radio system. Select components sized for 1/10 competition use.

How adaptable is the gearbox layout?

The gearbox accepts multiple configurations, allowing rear motor, 3-gear midship, or 4-gear midship setups to suit different tracks and driving preferences.

What maintenance should I perform after each race day?

Clean bearings, check for play in suspension and steering parts, inspect the differential and slipper for wear, and confirm screws are tight. Regular checks keep lap times consistent.

Are setup guides available for different track surfaces?

Yes. Seek setup sheets that cover carpet, artificial turf, and high-traction indoor surfaces to guide spring rates, ride height, and camber adjustments for the RB7.

Can I use the RB7 for casual bashing as well as racing?

While built for competition, the RB7 can handle casual driving. Expect to make protective changes and accept that race-oriented parts may be less tolerant of rough terrain compared to bash-specific models.
