Is anyone else having a problem with what I figure is the switch-over from sensored operation to sensorless operation (as you accelerate very gently)? If I gently increase the throttle from rest, I can find a point where even though I'm holding the throttle still, the power will be gyrating, accelerating and then slowing down, accelerating and slowing down, etc. in roughly half-second intervals. So I'm running full sensored mode, at least for now...
