40A Brushless ESC BLHeli_S Firmware Speed controller for Multicopters Drones MT40A-OPTO-BK2

BLHeli_S firmware is the next generation code, following the base BLHeli code.  BLHeli_S is designed for superior performance in multirotors, and uses hardware generated motor pwm for smooth throttle response and silent operation. All codes use damped light mode. Main features: Hardware PWM – smoother and more responsive motor response; Always use damped light (Regenerative Breaking) for better multicopter control; Code supports sync loss prevention – tuneable parameters to make your ESC work well in the most demanding applications (not just FPV racing); High resolution throttle steps; Supports Oneshot125 (125-250us), Oneshot42 (41.7-83.3us), Multishot (5-25us) protocols; Automatically detects input signal protocol on ESC power up; Beacon Function – your ESC will start beeping after a set time of zero throttle to help you find your quadcopter.
