These sine-wave drive ESCs increase power efficiency by capturing energy produced during deceleration.
Active braking provides a better dynamic response.
The 640S ESCs gather and transmit diagnostic information on the status of your propulsion system in real-time and can warn users if any motor is functioning abnormally during flight via the external LEDs.
An integrated spark proof circuit design prevents sparks and short circuits when plugging in your power supply and improves the reliability and life of the ESCs and connectors.
The E1200 features a duplex communication port, which allows users to easily upgrade the ESC firmware and change the color of LEDs.
Note: Accessories are sold separately and should be used with the DJI ESC Assistant. For more information, please refer to the E1200 user manual.
