Revolution Design Racing Products have introduced their new Brass Rear Motor Weight for the Xray XB4 buggy. It is an essential option part and should be on top of everyone's agenda when it comes to buying new stuff for the buggy. Weighing in at 26g and being made of high-quality brass the weight sits just behind the motor and it acts as a counter weight for the heavy LiPo battery that is located on the right hand side of the buggy. With the lighter motor the additional weight is needed to achieve a proper weight balance and thanks to its clever design it directly attaches to the chassis side guards using a single screw, meaning the weight is both easy to remove when needed while also securely fastened so it will not get thrown out of the chassis. The weight comes with RDRP's signature black and gold finish and it is a direct fit.
