If i undestand correctly sensorless does have sensors but there in the ESc allowing for more space inside the motor for more winding(i think thats the general theory)so a sensorless is not running blind BUT it has to do more computational calculation in order to "read" the position of the motor.
The novak has incredible throttle control as for determining the future of BL, mmmmm thats a tough one! imo sensored will be the way to go for the immediate future BUT sensorless is catching up real fast!
Seems that Hacker has already done away with cogging issue in there next-gen speedos!
Anyway the ball turns it still very existing watching a new technology progress and get better!
Randman: Very interesting news!
