20g centre ballast for fine tuning

This 20g centre balance weight is built for BD9-style RC chassis and provides a simple way to shift central mass without affecting left-right symmetry, useful when refining handling balance.

Mount the weight at the vehicle's centre to alter the centre of gravity slightly forward or rearward; this influences pitch and transient reactions during acceleration and braking. Being a single 20g component, it offers modest, controlled changes suitable for incremental tuning rather than major redesigns.

Compatibility is limited to listed chassis, so verify fitment before modifying your model. This product is an aftermarket accessory intended for model chassis use only.
Remark :
Due to limited stock availability, please notice that some Yokomo 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.

When is it appropriate to add central ballast during setup?

Add central ballast when you need finer pitch control or when small fore-aft CG shifts improve traction or stability; use it after baseline setup checks.

How should I assess handling changes after fitting 20g?

Perform controlled test runs and compare acceleration, braking and corner entry behaviour. Note small differences since the effect is subtle.

Does this weight mainly affect pitch or roll?

Placing mass on the centreline primarily alters pitch and fore-aft balance; lateral roll behavior remains largely unchanged if the weight is centred.
