App-Controlled Cat® D11 Bulldozer

This big set is one of the biggest Technic sets, and there’s lots of detail to it. You can control it through the app, which can make it move and do lots of things; for example, you could buy two and race them. I would buy this for ages 18 and up and then let children use the app. This set is also good for display. It would make a good birthday or Christmas present.
