Motors and speedo's without sensors tend to "stutter", particularly from standstill while the motor gets to the correct position in it's cycle in relation to what the esc is giving it.
I have never had, and never will have a sensorless motor. Nor should any other serious racer. IMO.

It's strange its only RC car motors that use sensored technology..... most boats, planes and helis all use sensorless motors
My son ran a Sensorless motor in his TC over the summer and placed second in his class.
Granted they do cog a little on power up or at low speeds, but in race conditions when do you run slowly?
