Specification of brushless motor and speed controller

Motor :

1. Working voltage range : 4.5V to 13V .
2. Max Power : 150W .
3. Max operation current : 30A .
4. RPM : KV2100.

Speed controller

1. Dimension : 40x27x10 mm .
2. Working voltage range :4.5 to 12.0V???
3. Max power :200W .
4. Max operation current : 25A .
5. Max Working temperature : 110 ???
6. Weight :30g .
7. Battery type (Low battery warning) : NiMH/NiCd .
8. Low battery warning Voltage :4.7 /-0.2V .
9. How the speed controller work :
   1. Connector the speed controller to Battery and motor,
   2. Switch radio on first.
   3. Switch speed controller On/Off switch to on , as the ESC detectthe neutral position signal from receiver , then the motor wouldrelease a confirm tone like  ‘ 123??????????????? ’, if notreceive signal or wrong signal, would not release tone .
   4. Auto detect neutral position of Radio, range 1.3mm to 1.7mm.
   5. If the car run in wrong direction, change any two motor wire,would be ok.
   6. As battery drop down than 4.7V, reduce speed to halfautomatically
   7. As run the car, if lose signal from receiver for 2 seconds,will stop car .
   8. As no play the car ,disconnect battery from speedcontroller.
