RE: Another brushless 'myth', lower KV = more torque
I wonder if the ESC is already kinda doing something like what I mentioned, limiting the power under 3000RPM as a safety measure to prevent large currents. There are 4 datapoints 3000RPM or less, some motor controllers or converters automatically have a 'soft start' feature. All of castle's have a 'starting power' parameter you can adjust, the novaks have something similar I believe.
It otherwise makes no sense, the shape of the torque curve under 3000RPM.
