Yes, It is software based.
The Turnigy K-force 40 is the ESC with the fastest response I have tested. It gave full throttle after the first PPM pulse. Having no filtering at all. See attachment.
However, after changing some settings it became slower than the Plush's, and changing the settings back to default did not change the respone back to original.
I will take a closer look at it when I get a new one.
