This is a Ready to sky 40A ESC 2-6s Li-Po Opto Brushless Electronic Speed Controller suitable for small to medium size drones upto 1000mm.


  • Using Multintegrated circuitopter special program, fast throttle response, surpasses all kinds of open source software.
  • Firmware was optimized specifintegrated circuitally for disc motor, and it has a very good compatibility.
  • Highly intelligent, strong adaptive capacity, reserve the timing setting item (height/middle timing, easy to use.
  • Throttle signal line is twisted wire to reduce crosstalk within the transmission signal generated by the copper, so that more stable flight.
  • Supports refresh rates up to 621Hz throttle signal, compatible with various flight controllers. (Note: the throttle signal over 500Hz are all non-standard throttle signal)
  • Using MOSFET special driver integrated circuit, its performance and stability far surpass the driving circuit with discrete components built.
  • Ultra-low resistance MOSFET, strong flow capacity.

Note: This ESC is not able to flash the firmware
