This is a replacement DJI 15 Amp Multi-Rotor Brushless ESC, intended for use with the E300 Tuned Propulsion System. This improved ESC, along with highly efficient and quick response algorithms, combine to provide drastic optimization of both motor and rotor parameters, all come together to enhance this propulsion system to utilize an agile thrust which gives the aircraft extra maneuverability and stability in wind and during descending. Also feature an electromagnetic compatibility design with a coaxial-cable, which work together to provide a calm electromagnetic environment for the airborne sensors.
