I am selling these items as I am retiring from Mini 4WD. I have kept them in storage for a while, but no longer need them, so I hope someone can use them. Regarding the batteries, the Yokomo HYPER3900 may not be usable as the charger's light doesn't turn on when I try to charge it. The other one seems to be rechargeable, and I confirmed the motor works. Please check the images for everything included. Also, please note that all sales are final, and no returns will be accepted.
