Neat truck, great project. It's nice to be able to build something and actually play with it when you're done instead of just sitting on a shelf (Lego set). My son is 12 and was able to put this together in almost a day with just a few questions. Once completed it didn't work properly as others have pointed out. Step #22 shows connecting the two steering servo pieces together, there is a note to make sure the arrow lines up with the stop before you connect it. Of course it wasn't in the middle. After the boom levels itself and clicks again, it works properly. The app works well and drives the truck well. It's not super fast, but I don't think you want it.
