The throttle response is much smoother than a conventional 2-magnet pole system. It's like driving double cream. Not at all peaky. I run a lot of sensorless systems anyway, and the only problem I have with them is the sometimes slightly rough start up. This set up doesn't suffer from that, you would never know it was sensorless. I think because there are so many more poles and at any time the magnets are closer to a sensing pole, the induced EMF is stronger at a given rotating speed. This seems to give great feedback to the ESC and as a result, low uncertainty on rotor position. As I said before, you can enclose the motor in your fist and smoothly throttle up, and it will just start smoothly turning.
