Drive fearlessly and punch that throttle! The MAMBA MONSTER X 8S W/1520-1650kv SENSORED COMBO is intended for use in 1/6, 1/7 and 1/8 scale vehicles weighing up to 18 lbs. and running up to 8s LiPo. (Examples include Losi LST2-E™; Arrma™: Limitless™, Typhon™ 6s, Kraton 6s™, Kraton EXB™, Infraction™ Felony™ 6s, Notorious 6s™, Talion™ 6s; Kyosho Inferno™, Traxxas: E-Maxx™, E-Revo™, UDR™, Summit™; Redcat Shredder™) SmartSense™ mode uses the motor's sensors to start the motor to provide smooth starts, excellent torque, and low-speed drivability. You'll put more power to the ground, where it should be, instead of wasting it through raw heat and RPMs. The 4-pole 12-slot 1520-1650kv sensored motor design boast exceptional efficiency, and the oversized NMB bearings and vibration dampening system ensure the longest bearing life possible. High-strength, high-temperature grade neodymium sintered magnets combined with a high-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions. You will reap the benefits of longer run times on one battery and a cooler running motor that can be pushed harder. 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. These software advancements work in parallel with a unique open housing design to allow increased directional airflow to cool critical components. With the integration of a 40mm cooling fan and a forged elliptical fin heatsink, the design maximizes airflow throughout the system, taking thermal performance to a whole new level. High-performance demands high quality and this ESC was designed with durability in mind. Constructed around a robust aluminum casing, the epoxy potting guarantees protection around the circuitry and ensures all-weather use. Mamba Monster X 8S is a workhorse, it will dominate in the harshest of environments
