I would think that in suck a light car it would be able to just lock up the tires...nope! Barelt stops the car. Even if I'm doing about 3-5MPH is still takes a good 10-15 feet for the car to stop.
I really don't understand why braking with sensored motors is so much weaker but maybe because they have smaller rotors made with weaker magnets.

thanks for the post. that's exactly how i feel. maybe the answer is to try and find a 4 pole,high kv motor for racing my b4 and b44 and just abandon the sensored motors.
