Improving weight distribution is one of the best ways to increase the performance of your scale truck. Our N2R Low CG Battery Tray for the Element Enduro moves the heaviest component of your truck, the battery, down and forward by 5mm to lower the center of gravity and increase forward weight bias. The tray works with just about any size pack you'd want to run, big or small. We've even incorporated a extra wide slot under the tray to hold your battery strap in place along with your servo and accessory wires.
