An opto ESC isolates the high-power side (battery and motor) from the signal side (connection to the receiver) by internally transmitting the receiver throttle signal from the input side to the output side of the ESC through an opto-coupler.
ReadytoSky 30A 2-6S ESC 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 30A 2-6S 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 2-6s Lipo Battery.
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.
