  1. Rik Meloen

    I bought this brushed dc motor for my DIY electric skateboard, and it has been fantastic. It delivers excellent acceleration and maintains a consistent speed. I’m thrilled with its performance.🎉

  2. Leon Burlsworth

    Valid rs390 dc brush motor, very powerful when fed with the appropriate amperage. For example I tried it with a 7.2 volt 1.5A power supply and the motor ran well as speed and was strong with certain force, they do not overheat I would say excellent!
