Adjust RB7/RB7SS Balance with Kyosho UMW751

The Kyosho UMW751 - 32g Battery Weight for RB7/RB7SS is engineered to sit beneath the battery and refine the car's centre of gravity on the Ultima platform. Used correctly, it helps the vehicle track truer through fast bends and tight transitions.

Performance Benefits

This 32g unit is sized to add useful ballast without overloading the chassis, improving tyre contact and reducing roll on high-speed corners. It is particularly effective on technical circuits where predictability matters.

Simple Installation Steps

To fit the Kyosho UMW751, position it under the battery area of your RB7 or RB7SS and secure it so there is no movement. Check clearance under the body shell and perform a test run to confirm the handling changes.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I use this with lightweight batteries?

Yes, adding this weight can help balance setups that use lighter packs, but verify battery clearance and balance effects before committing to race setups.

Does it affect tyre wear?

By improving contact patch stability, the weight can lead to more even tyre wear, though overall wear will still depend on driving style and track surface.

Is special hardware required to fit it?

No special hardware is typically needed; use existing battery straps or double-sided tape to keep the weight secured. Ensure it cannot shift during impacts.

Will this change be reversible?

Yes, the modification is non-destructive and can be removed quickly if you wish to return to the original weight distribution for different tracks or conditions.
