This is a set of optional parts for R/C or Mini 4WD car models.
This is one incredible little electronics package. This advanced speed controlling system dynamically controls the gate of the Field Effect Transistor in response to variations in the motor speed which allows very accurate control of the motor speed with minimal energy loss. This system can work with any motor that can be battery powered. An absolutely amazing piece of work.
