I believe this was purchased about 10 years ago. I don't have batteries on hand, so I haven't confirmed its operation (it was working when I checked about a year ago). The trailer itself uses 6 AA batteries. The car on the trailer uses 3 AA batteries. The remote control uses 1 9V battery. You switch between controlling the trailer and the car with the switch on the remote control. The front of the trailer has a disc launcher (green discs are launched by pressing the round button on the remote control). As you can see from the underside of the car, the right rear screw is missing, and the battery cover screws have been replaced with others (this does not affect use). I will clean and pack it before shipping. No returns or exchanges. Please refrain from purchasing if you are overly concerned about condition. If you have any questions, please feel free to contact me in the comments section. #RadioControl #Trailer
