[QUOTE=COBRARACING;5414048]the sensor systems are crap and dont work no matter what .just use it sensorless and use a heat sink and fan thats the best way .

When i designed our 120 amp brushless esc i designed it sensorless and the reasons why is that the motor sensor must be the same resistance(the thermisters must match and be of a low tolerence and specs of the esc and i dont make motors i can tell you this most companies who have esc and motors i can guarantee you that motor and esc are not in the same spec or made from the same factory as a match for the sensor to work properly .The only one probably is Novak were everything is matched and made under one roof.In saying all this im sure you can give the esc company a motor from another company and they can try to match them and i mean try no guarantee it would work

other than the sensor part im sure all motors and esc's are all good from all companies

the best way to overcome all this is for companies to forget the sensor system and build a thermistor circuit on the motor itself that you can reset with a press of a little button on the back of the motor.
