Features:1, Specifically optimized firmware ESC, the ESC has a very good compatibility;2, Highly intelligent, adaptive ability, extremely easy to use;3, Throttle signal line is a twisted pair, copper wire to reduce crosstalk signal generated 4,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 throttle are all non-standard signal)5, Use MOSFET special driver chip, performance and stability far beyond the driving circuit with discrete components
