efficiency 100% N-FET design. Highest accuracy with Crystal Oscillator (Temperature won't affect the PWM operating range like other cheap ESC's). No low voltage cutoff, because any cutoff in a multirotor = crash.
No over temp cutoff, because any cutoff in a multirotor = crash.
Super high refresh rate, no buffering of the input signal, resulting in more than 490Hz response rate.
16KHz motor frequency, giving fastest response of the motor, and quietest operation as well (no 8KHz squeal). Super simple, foolproof operation! Nothing to program other than the throttle range.
Don't buy a 30A multirotor ESC that doesn't meet all these criteria!
There are a lot of low quality 30A ESC out there! ESC
