This is a top-performance motor designed with an extremely low kV value and an ultra-high voltage platform (12S-24S). It was created specifically for applications with extreme demands on pull, efficiency, or both, providing an unparalleled torque generation foundation that allows the motor to smoothly drive giant blades at extremely low speeds (typically a few hundred RPM). This “low speed, high torque” mode is ideal for those seeking maximum endurance or quiet operation.
