Under the lid it looks like a big hunk of plastic! Yeah, the cooling head for the esc is cheesy as can be....so is the molded exhaust stinger.
It looks like it'd be fun, but I'm going for the 18T. Plus, it's 1/16 so you couldn't race it with the 1/18ths. I wonder what the $ tag will be on that thing. It's Kyosho, so probably not to cheap!
