Craig, I've been running sensorless. In fairness most of the others are running sensored - but i like the torque of sensorless. Something like low 6's on gearing and it should be ok - i ram 6.0 on an 8t delta wind - which isn't a million miles off or a 4.5.
so it seems that the last 2 updates have done nothing really, just for spec speed control identification and the button on/off problem. However I feel most people think that that on/off function is not working is because they have not set it to as a switch from the AS.
