Or you could do it this way. There’s a lot of photos of this one, but I still am not entirely certain how the actual tracks are operating. As far as I can tell, he’s using pieces of straight RC track, but a lot of them are curved in ways that to my knowledge could only be achieved by warping the parts to the desired shape by heating them up first. It’s an impressive build, but that’s definitely not something I have any interest in trying myself.
