This is the Tekin ROC412EP 2Y 1800Kv Brushless Crawler Motor. Tekin's Element Proof ROC412 HD offers protection from the elements, giving you the power to take on the trails or track without fear of water, mud or snow! Designed for heavier trail or rock racing rigs, the ROC412 HD delivers more torque and more power on demand. The HD lineup offers the same trusted kV ratings so you can maintain desired speed and input voltage but the longer design offers more grunt when you need it. Using a 4-pole 12-slot motor design based on the award-winning T8 Series motors, the ROC412 HD harnesses the benefits of brushless efficiency and extreme amounts of torque to stay out on the trail longer with more power on tap. Couple the ROC412 HD with an RX4 Speed Control for the smoothest crawling system available! Crawling, Rock Racing precision, protection from the Elements and raw power are at your disposal!
