Question: What exactly does opto-isolation mean for R/C? I know what it means in the electronics world, but am having a hard time firguring out how it relates to BEC use...

As for the second part, I don't have a clue. I'm still trying to figure out this mystery before I do any more figuring.

Let me help you out:
Opto Isolation as relating to R/C is the same OI as in all other electronics pertaining to OI. OI allows a low voltage/power circuit to control a much higher voltage/power circuit. Your Opto-ESC contains two basic parts, the Control side and the Power side. Between the two sides are three OI Semi-Conductors. Three because the ESC has three phases, usually. Each OI SC contains an Infrared LED and an Infrared Phototransistor. The Control side of the Opto-ESC simply turns on each IR LED in sequence, which turns on each IR PT in sequence, which activates each phase of the Power side, yes, in sequence. There is absolutely no hard-wired connection between the Control side and the Power side of the Opto-ESC thus you need a reciever pack to supply power to the Control side of the Opto-ESC as well as the reciever and servos.
