Lack of high end sensored motors most likely stems from the lack of high end sensored speed controllers. Griffinru made a feigao work with a novak hv using the hv motor as a sensor and putting the leads to the feigao. Neither are high end, but I bet it had great low speed driveability! The novak esc is supposed to be quite good, just the motors are a little small for heavier applications.
