The rocks buried beneath the dirt and sand did me in, http://www.pbase.com/calvinwill/rocks the rocks never did get stuck in the sprockets, it chewed right thru them, but in doing so it stretched the right tread to the point it needs replacing, the photo showing the rocks in the sprocket was taken when the batteries drained, otherwise those too would have gone around and been spit out of the sprockets. Cap, you have to find some sand or dirt somewhere to see the true power of this tank, you need to get out of that tall grass
