The sweetspot only lands on 190KV (@12S) if you have full torque and full speed the whole time. So for high speed hill climbing for example. For mountainboarding in the forest, or racing super aggressively, it should be fairly close too. For just going fast on roads… It’s significantly lower KV, because while the speed is sustained, the current is not. I made a log when I’ve gone 50kph or so on my 140kv 12s FSBH build and I’ve actually calculated that I lost 25% more energy to iron losses than I did to copper losses!
