T-Works T4 & BD10/9 14g tungsten balance weight
Coming from T-Works and made for the use with the Xray T4 and Yokomo BD10 and BD9 touring cars is a 14g tungsten balance weight. Made of super-heavy tungsten material the weight is compact yet very heavy for its size, making it the ideal balance weight for the machined under-battery chassis pocket opposite the motor. It attaches using a factory-applied adhesive tape and it comes in handy especially when running lightweight low-profile battery packs. The weight is usable with the T4 2020 down to the 2018 kit as well as the Yokomo BD10 and the older BD9.
