New adjustable weight receiver battery mount for Lab C03 and C803 cars. Machined from carbon fibre the mounting plate utilises two movable 13.5g tungsten weights that allow to adjust the overall weight bias while adding weight at the lowest point of the chassis, ensuring a lower overall centre of gravity. The carbon fibre mount comes with a machined lot for the battery tape, making for easy and secure receiver battery mounting and the 13.5g weights are understood to also become available separately to further up the weight.
