I have just needed the rotor from this motor due to my 500KV motor's rotor was bent after one crush and I needed replacement. Quite nice quality. I don't know about this version but 500KV is very powerful and good performing motors but not available anymore in here.

I haven't tested any of them yet but the built is pretty good for the price. racerstars made good inexpensive products.
