6X for SimonK 30A ESC Brushless Speed Controller BEC 2A for Quadcopter F450 X525

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! to program other than the throttle range.
