The new generation features a high airflow arrow design with large openings in the machined aluminium can to guarantee maximum cooling efficiency, a lower weight and minimised power fading in high ambient temperatures. The redesigned stator helps to achieve a much lower internal resistance, increasing in torque which enhances the overall performance. The RS-Tune motors are specially designed for most Asian stock racing classes as they are already equipped with a standard (V2RSS123) rotor, that keeps them within the KV and Amps requirements. The motors are available in 13.5T, 17.5T and 21.5T specification.
