40A 2-6S ESC 3.5mm Banana connector
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 40A 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 40A 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.
If you are wandering to build a drone and don’t know what will be the best ESC for you then worry no more, we have got your back. At Robu, we have everything for you to get started with your drone project.
Note: Black wire does not include with ESC.
