Losi Micro DT
This DT is big time RC in a tiny scale. At 1:36 it'll fit into your hand easily. This thing is fast and tough. I have jumped it, slammed it into curbs and nothing has broken yet. I added the Li-Po battery pack and it increased the speed and run time dramatically.
The only downside to this is maintenance and repair and most of that is because of its size. The e-clips for the wheels are a joke. The threaded axle upgrade will take care of that problem, but that should have come standard on the truck.
Overall its great fun. I bought it for my son, but I find myself driving it more than he does. *
