With a 30A capacity, it includes soldered 3.5mm gold female plugs for easy motor connections. Its crystal oscillator ensures temperature stability, while a refresh rate exceeding 490Hz and a motor frequency of 16KHz provide unmatched responsiveness and quiet operation. This pack of four controllers is perfect for enthusiasts looking to enhance their flying experience. ## Description for sale is 4pcs 30A SimonK firmware Brushless ESC. Soldered with 3pcs 3.5mm gold female plug, very convenient to connect motor. 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.

PWM stands for Pulse Width Modulation. This is a not an analog signal. Google Radio Control PWM. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ok esc not for sailplane *by J***R on October 15, 2020* Work ok but cannot program it I needed brake function,instructions make no sense badly written ### ⭐⭐⭐⭐⭐ Bidirectional! *by D***. on March 29, 2022* Simonk 30A Bidirectional Tutorial: The beeps are quiet, hold the motor against the table to make them louder.
