30A ESC for Multirotor.:

This hardware, with the Simonk firmware, gives you the perfect solution for multi-rotor use. Highest Efficiency 100% N-FET design. Highest accuracy with Crystal Oscillator (temperature does not affect the PWM operation area as other cheap WSA). No undervoltage lockout, because everyone in a cutoff Multirotor = crash.30A ESC for Multirotor.

Product descriptions 
No overtemperature shutdown, because any shutdown in a Multirotor = crash. 
Super high refresh rate, no buffering of the input signal, resulting in more than 490 Hz response rate. 
16KHz motor frequency, thereby fastest response of the engine, and silent operation as well (no squeaks 8KHz). 
Super easy, simple operation! Nothing to program other than the throttle region
