Team Associated B4/T4 centered ESC mount
Team Associated introduce the Factory Team centered ESC mount that allows racers to mount their vehicle’s speed controller in the center of the car against the rear bulkhead. In addition, the plate makes room underneath for the receiver when using shorter packs. These changes move more of the weight to the center, allowing the vehicle to change directions faster. This advantage is even more pronounced on high-grip surfaces. The mount is designed for the use with Team Associated’s B4 and T4 platforms and is also usable with standard size 2S packs and comes including mounting hardware.
