Would a sensored brushless motor work with a sensorless brushless ESC? I have a Hobbywing brushless sensorless esc without a sensor cable. I would like to try out a sensored motor within the esc's limits and see what difference does it make.

Yes, a sensored motor should work with a sensorless ESC so long as you don't use the sensor cable. I don't think it will make any difference (sensored motor vs. sensorless motor), though, considering a sensored motor without a sensor cable is just a sensorless motor
