This is a great tool for testing your sensored brushless motor's hall sensor. It will quickly and easily allow you to determine if there are any problems with your motor.

Simply connect the sensor cable from your motor to this device, turn it on and slowly spin the shaft while watching the 3 LEDs. As you spin the motor, each LED should light in series as your spin the shaft. If all lights stay constantly lit, do not light at all or only light at one point of the rotation, your motor sensor has an issue.

This motor sensor tester is powered by a standard 9V battery (included) and can be replaced by unscrewing the back cover. This is a must have for any R/C tool box!
