This is a "Must Have" for all the X4 Xray drivers that are looking for the maximum performance, starting from the details.
The BC-X4 was developed together with professional drivers, to achieve the best possible performance. The machined aluminium case gives the servo a stealthy and sleek look. It's also very weight efficient, thanks to it's integrated mount. This gives the car the lowest possible CG, and centralized weight. The integrated mount also offers unmatched rigidity, which gives an immediate improvement of the car's steering response. The included bridge allows for maximum adjustability out of the box, with both a forward- as well as rearward mounting option. This makes it quick and easy to fine tune the flex setting of the car.
