100% correct.
The unfortunate thing re: the Yeah Racing esc is that you've headed off the beaten path a bit...YOU may end up being the guy who experiments with it and figures out what (if anything) will make it work with the 1s LiPo. Thus far the esc's I've SEEN work with the 1s setup are the Novak 4-cell (easiest) and the Tekin RS (simple workaround that supposedly won't be necessary once the new firmware is out). I am aware from my racing friends in Denver that they've figured out how to work around the LRP/Nosram esc's too (probably a similar process to the Tekin). I believe I've heard that folks have made the SpeedPassion work too.
I know nothing about the Yeah Racing esc and know of nobody who runs one. In fact I'd never heard they had an esc until you asked. As I said, I'm guessing you're going to be the test subject.
