Built specifically to handle the rigors of large, power-hungry trucks, the Mamba Monster speed control is ready for 6S LiPo power with its massive 6.5mm gold-plated connectors, high-efficiency heatsink, integrated cooling fan and heavy-duty components. The speed control sends its power pulses to a Castle 2200Kv 75mm motor, designed specially for maximum performance and reliability with 6S LiPo power in torque-hungry applications. The aluminum motor can is machined to act as a massive heatsink, high-grade bearings deliver maximum efficiency, and high-strength Neodymium magnets give E-Revo brushless edition outrageous torque. To resist the twist, a beefy 5mm shaft transfers power to Brushless-Ready transmission.
