7xl specs?

What would the loaded kv rating of a 7xl be? I found that it's listed to have 2382 rpm/v, but remember hearing that Feigao rates their motors without load. Also, what do the bearings max out at, 50,000 rpm like the rest of the Feigaos? I would guess that I'd max out the cell count on my controller before I totally tapped the power of that motor, who knows whether the vehicle would take it too!
