KM Racing NT1 & MTX-4 Copper Battery tray
In addition to the version released earlier for the Kyosho V-One RRR, KM Racing have come out with these new battery trays for the Xray NT1 and Mugen MTX-4. Made from brass, the tray brings weight to the lowest and most central point on the car, which not only helps increase chassis rigidity but also helps stop the car from traction rolling in high grip conditions. Machined with 2 grooves for tape to mount the battery, it sports the KM Racing logo engraved on the bottom.
