Tracks work best when they are in a configuration like a tank, for a Mini 4WD you would need a front idler wheel, a rear sprocket, and some road wheels (let's say 1 at the front and one at the back) to give it that shape like a W. That way it will have better ground clearance due to the shape of the track and, if you can keep the structure within the tracks, it won't have issues with thing getting stuck in the middle. Regardless, this was a fun video and I had a good laugh when you ended up with something that looked like an Object 279 :D
it's amazing to see a normal mini 4WD car can turns into something different by a person's creativity that turn into reality by using modern machine tools, awesome!
I came to this video expecting to see some really cool mini 4WD... And I did! Great work! But I also didn't expect to learn the origin of the name of the Yu-Gi-Oh archetype infinitrack
