Experience higher efficiency, advanced features and improved optimization for your stock upgrade or build with Castle’s legendary brushless power. The MAMBA MONSTER X 8S, 33.6V ESC W/1520-1650KV SENSORED COMBO is a perfect upgrade for 1/8, 1/7 and 1/6 scale vehicles weighing up to 18lbs and up to 8S LiPo. The 1520-1650Kv has all of the secret sauce that the big brother 1717-1650Kv has, but in a more compact diameter, fitting into smaller spaces without modifications to your chassis.

The MAMBA MONSTER X 8S utilizes Castle’s breakthrough technology CRYO-DRIVE™. By reducing the rate at which the ESC heats up and removing heat more efficiently, your setup will be able to handle higher gear ratios, in heavier vehicles, with longer runs.
