Featuring a more compact integrated design with a length of just 48.5mm, this motor is 9.5mm shorter than the Pro Standard version and 1.3mm shorter than the AXE 540. Fits nearly all 1/10th scale vehicles on the market. This ultra compact 2-in-1 motor and ESC allows for super clean installation and wiring. The ESC supports 2-4S Lipo batteries and delivers a maximum continuous output current of 50A. Combined with its compact designs, it meets the demands of most 1/10th scale crawler applications, providing stable, consistent power without performance drop-offs. By connecting the yellow AUX CH signal wire to an unused receiver channel, you can adjust ESC parameters (like drag brake force) on the fly from your radio. On trail tuning has never been this easy. The power system uses FOC ( Field-oriented control) drive, delivering significantly stronger low-speed torque and smoother performance than conventional sensored systems. It outperforms traditional brushed power systems and eliminates motor noise for near-silent operation, allowing you to fully enjoy the experience. The ESC features an intelligent torque output and speed closed-loop control system that automatically adapts to changing terrain conditions. The ESC increases output torque to overcome obstacles when encountering resistance. On descents, it reduces torque output and stablizes vehicle speed, making driving remarkably simply. The entire power system is rated IP67, delivering outstanding waterproof and dustproof performance. Whether in rain, snow, mud, sand, or standing water, it handles harsh environments with confidence. The ESC includes a powerful built-in BEC capable of delivering up to 10A of output current, with selectable voltages of 6V, 7.4V, or 8.4V. It effortlessly powers standard and high-voltage servos, as well as accessories like lighting systems and winches. NOTE: The IP67 rating protects against splashes, water exposure, and dust under normal use but is not permanent. Protective performance may decline over time due to aging.Do not submerge the product for extended periods, as this may cause damage. NOTE: When set to Normal mode, constant speed control is disabled, resulting in behavior similar to a brushed system.
