this one took me a while to make, but when it was done it looked really cool and it is extremely tough! I don't now how it got so sturdy but this thing can hit walls at full speed, or be rolled off a table and be just fine.
It is loded with all sorts of gizmos inside. it also has six tires (from the spirt rover set) alnong with shocks (also from the rover set) that alow it to go off road. on both sides and the back it has misssles launchers. all and all it turned out better than I had hoped.
