Don't have a link, but first there was a lil losi crawler. Then he went to an axial and replaced the plastic chassis with an aluminum one. There was a time lapse and they explained the advantages. He didn't really drive either of them. After the Axial, he had a gube chassis crawler with a transfer case. I don't know what it was called; the chassis was red. He assembled that one and then he drove it. He locked the rear wheels and "dug in" to the ground and said it's just like a real crawler.
That nice showhost wasn't on though...
I'm not sure how long she's been gone.
