One of the comments below the video says this:
[font=Comic Sans MS]"For those searching the internet trying to find these micro rc in this video. Only a few of the semi trucks can be bought on eBay. The rest of what you see. Is hand crafted using 1:87 scale toys or ho train scale models. EBay,Amazon,aliexpress.com and pretty much any where else will carry the display models only. The motors, gears,axles, nano servo, receiver, radio, batteries charger, plugs/connectors , led bulbs, etc. Can be bought on eBay or most China commerce related websites. It would be a great idea to watch videos on restoring match box cars/hot wheels to find out what other parts , tools, and supplies you'll need. It will be a great idea on watching video on scratch built 3 print rc cars. In closing. I BUILD these micro rc's at home. Each one cost about $150 to $200 to build. The tools I use cost about $2200 Total. The small cnc metal lathe cost $762.00. There's really no one place to buy the stuff needed to build your own 1:87 scale rc model collection. Just learn what you need and how to go about getting it done is all you need. Best of luck to ya."[/font]
