If you slowly press your throttle with your senseless bl system you will see that the car jumps 'the best way i can describe it' if you had a sensored motor it will not do this.
It depends on your esc if it can run both senseless and sensored motors. If you have the senseless xceleron esc you can not run sensored motors.
I was running the same system you running and it used to do that jumping when i slowly pressed on the throttle and i brought it back and bought me a sensored system since i was planing on racing but if you just bashing dont worry about it.
