BRUSHLESS MOTOR SPEED CONTROLLER, Voltage : 2-3S LiPo

30A ESC for Multirotor 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 under voltage lockout to avoid crash. No over temperature shutdown, 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).
