    100% brand new

    for sale is 4pcs 20A SimonK firmware Brushless ESC.

    Highest 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.
