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