Because many peoples asked My about RPM of motors I wanted to test speed of popular 130 type motor and 180 type from WPL KIT
To test it I buy Tachometer:

This allow Me to test speed in RPM off everything.
To test motors I used My power supply and I set it to 6v (because this is voltage of that popular batteries) and to max amperage (it's about 4,5A) but You can see on movie that is max on high torque
Here is link to that N20 motors (You can chose speed there)
