Besides which, if you are crashing hard enough to stop your car more than once per run, you are not going to win anyway.
I guess sensorless are perfect if you don't crash and don't need low-speed driveabilty, otherwise any problems will be a disadvantage when racing against sensored motors.
Sensorless even with the best programming cannot be as good as sensored for the best low-speed control and driveability. It will be interesting to see which wins most on the track and which is favoured most amongst drivers.
BTW nice to see another new and 'different' sensored motor in the brushless market, with knowledge and experience behind the design.
