That will be a 12 pound aluminum brick. Most here would reccomend staying away from aluminum for bashing. It tends to be pricey, break and once bent aluminum stays bent. Upgrade with high grade plastic if you want to use the truck for bashing.
I recently purchased an Aluminumized Revo 3.3 and one of my stipulations was that the seller had to give me all of the stock plastic. She is now a leaner meaner bashing machine. I've removed all of the extra metal and unshelf queened the truck. It had aluminum bumpers, skids, steering, body mounts, piggy back shocks with super stiff springs, etc and to top it off a steel roll cage. It sure was pretty but it ran like a brick and I wouldn't even want to imagine the carnage a good bashing session would have caused.
