What happens if you try to overdrive your ESCs (e.g. put a big motor on a 10A ESC and throttle it all the way up)? Will most ESCs limit the current, or will they deliver the current and possibly overheat?
I think my ESCs may be limiting my payload capacity, but want to figure out if that can actually happen before I upgrade them. If they are underrated, would they limit my thrust at max throttle, or would they just overheat?
It is mostly a heat issue. Unless you're doing something really crazy, you can overdrive them some, and check the temperatures after flying.
