The 4pcs EMAX Lightning_S 35A (BLHeli_S) ESC OPTO 2-6s F396 MCU for RC Multicopter QAV250 is a high quality BLHeli_S ESC with hardware generated PWM synchronous to MCU that yields ultra-quiet motor performance. It utilizes high-performance EFM8BB2 50MHz MCU. Incredibly mini and light, it weighs only 14 grams including heatsink and all wires. And it is FW upgradable via signal wire (BLHeli_S HEX needed). Hardware PWM refresh rate can reach 36KHz with BLHeli_S. Faster rate allows more input signal in same given amount of time resulting in smoother and more responsive throttle.
