Just wondering if anyone knows of a dictionary/encyclopedia sort of thing (online) that explains a lot of the mysterious terminology used in ESC instruction manuals?

EG: Drive frequency. I've had this explained to me as perhaps providing a little more punch out of the corners, or it just makes things smoother when it's turned up. Can't seem to find the true, concrete answer.

So, if you know of such a resource, please let me know.

Thanks!
