ReadytoSky ESC 40A 2-4S Electronic Speed Controller is specifically made for quadcopters and multi-rotors. Which provides faster and better motor speed control giving better flight performance compared to other available ESCs. ReadytoSky 40A 2-4S ESC comes with a multi-integrated special program, fast throttle response, surpasses all kinds of open-source software. Firmware was optimized specifically integrated circuitously for the disc motor, and it has very good compatibility and this ESC is compatible with 2-4s Lipo Battery. The throttle signal line is twisted wire to reduce crosstalk within the transmission signal generated by the copper, so that more stable flight. This ESC Supports refresh rates of up to 621Hz throttle signal, compatible with various flight controllers. (Note: the throttle signal over 500Hz are all non-standard throttle signal) Due to ultra-low resistance MOSFET, it has a strong flow capacity. With MOSFET special driver integrated circuit, its performance and stability far surpass the driving circuit with discrete components built. Package Includes: 1 x ReadytoSky ESC 40A 2-4S Electronic Speed Controller
