How do I identify what protocol my esc are using?  I've upgraded my FC to a Kiss.  But I don't know what protocol to use for the ESC mode.

These are from my Storm 250 SDR Pro.  I think this is the link.  http://www.helipal.com/storm-multirotor-...3s-4s.html

And more importantly, when I need to replace one will I need to replace all?  Or can you mix and match?

Your ESCs have Simon K firmware. You will have to use PWM.

If you upgrade, you should upgrade all. I don't suggest you mix and match.
