Notes on reflashing ESC firmware

A couple of random notes about this.  The firmware mentioned is good for multicopters as it supports a very high update rate.  The code is fast, can support a prop speed of 120,000 RMP... yikes!  On the thread, someone notes "Finally that annoying 8kHz whine from the motors is gone, and motors are very smooth."
