Team Associated have added to their Factory Team range two news brass arm mounts for the RC10TC6.2, RC10TC7, and RC10TC7.1. Both outer and inner arm mounts are machined from high-quality brass, come laser-etched and increased mass. Each outer arm mount is 7 grams heavier than the aluminum version. The inner arm mounts are heavier than the aluminum version by 2.5 grams each. A combination of these mounts, or completely replacing the stock mounts, helps with tuning the overall center of mass. They are available in pairs.
