Excellent performance, specially designed for 1/10 STOCK racing. The innovative outer diameter structure of fully exposed stator core maximizes the heat dissipation area and the rear end of the motor is a big opening structure to further improve the heat dissipation effect. Dual sensor interface design to meet various wiring/layout requirements. The special copper bar is customized and the spacing of copper bar is widened, which greatly facilitates the operation of soldering wire. The built-in high precision Hall sensor combined with the high precision and balanced rotor guarantee outstanding linearity of the motor. The use of high-performance stator core, 220℃ high-temperature-resistant enameled wire, high precision and high strength bearings, and copper solder tabs with super current endurance guarantees outstanding performance and super durability.
