This is a ReadytoSky 30A 2-6S ESC
The opto ESC (Electronic Speed Controller) isolates the high-power components (battery and motor) from the signal components (receiver connection) by transmitting the throttle signal internally from the input to the output side of the ESC through an optocoupler.
The ReadytoSky 30A 2-6S ESC is specifically designed for quadcopters and multi-rotors, providing superior motor speed control and enhancing flight performance compared to other ESCs available on the market.
The ReadytoSky 30A 2-6S ESC features a multi-integrated special program, offering fast throttle response and surpassing all kinds of open-source software. Its firmware is specifically optimized for the disc motor, ensuring excellent compatibility with 2-6S LiPo batteries.
With its ultra-low resistance MOSFETs, the ESC has a strong current capacity. The special MOSFET driver integrated circuit enhances its performance and stability, surpassing those ESCs using discrete component driving circuits.
If you are planning to build a drone and are unsure which ESC to choose, worry no more. At Robu, we have everything you need to get started with your drone project.
Features:
- Specifically optimized firmware ESC, the ESC has a very good compatibility
- Highly intelligent, adaptive ability, extremely easy to use
- The throttle signal line is a twisted pair, of copper wires to reduce the crosstalk signal generated
- Supports up to 621Hz refresh rates up to the throttle signal, compatible with a variety of flight control (Note: More than 500Hz signal of the throttle are all non-standard signal)
- Use MOSFET special driver chip, performance, and stability far beyond the driving circuit with discrete components built
