My lehner basic xl 1200, runs 1200kv (rpm/v) its rated for 50,000 rpm's (I think), I am running it at 22,200 RPM's, I am not overdriving it. Now if i were to do say, 12s lipo (44.4v), thats a different story. Thats 53,280 RPM's, and thats overdriving that motor. Right now, I'm at less than half the rated max RPM of this motor
Exactly. They also have to keep in mind that the lower Kv motor will produce more torque and electric motor has the advantage of making power from torque. My 1521/1Y (1577Kv) is doing great with 5S. The Neu 15 series are rated at a max of 60,000rpm and I saw what my motor can do with 10S lipos and it is just out of this world.
