Refine RB7/RB7SS Handling with Kyosho UMW751

The Kyosho UMW751 - 32g Battery Weight for RB7/RB7SS is built to sit under the pack and refine the centre of gravity on the Ultima chassis. Fitting this compact weight helps the car settle into corners and maintain composure through quick direction changes.

Track Advantages

At 32g this weight brings measured mass that enhances traction and cuts down on body roll without making the car sluggish. It is most effective on technical layouts where keeping the tyres planted matters most.

Fitting Notes

Install the Kyosho UMW751 by positioning it under the battery and checking it is flush against the tray. Secure with tape or straps and confirm it cannot move before running to ensure consistent handling improvements.
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.

Is the UMW751 compatible with aftermarket batteries?

It fits by shape under most battery packs used in RB7 and RB7SS setups, but measure clearance with thicker aftermarket packs to be sure of a correct fit.

Will adding weight affect acceleration?

A 32g addition has a minor effect on straight-line acceleration but the trade-off is improved corner speed and stability, which can lead to faster lap times overall.

Can I stack multiple weights?

Stacking increases ballast but may interfere with battery fitment and handling balance. Test incremental changes rather than large jumps to find the best setup.

Does it need maintenance?

The weight itself is maintenance free, but check mounting and any fasteners regularly to prevent movement after hard runs or impacts.
