Some castle hv esc.
,s have an currentlimiting funktion

How does that work ? How can the esc limit the amount of current flowing thrue it ?
I,m hinking of building a brushless brushcutter/weedwacker with a rotomax 50cc outrunner on 12s lipo in it

But i only need 2800w max poweroutput from it and it can handle 5000+ watts.
So it chould run very cool and effichent if i limit the current so that it only putsout 2800w tops?
