This Chariot is solid aluminum, and built by a friend of a friend. He builds tuna towers for fishing boats making this chariot extremely light, weighing approximately 70 pounds. I think this is a thing of beauty and a real kick to drive. Currently it is set up for a pair, but we have it in the works to set it up for a four abreast. There are three levels of adjustment to allow for various size minis. We also plan to lower the axle for a lower center of gravity and make it easier to balance. I think this vehicle is a thing of beauty and it's a real kick to drive.
