RE: What is your favorite vintage RC?
Favorite that I've owned: Tamiya Brat! I consider it to be one of the earliest examples of a SC truck, though it predates the modern phenomenon. That truck isn't made of plastic and metal, it's made of fun and awesome.
Favorite that I've not owned: Original RC10 goldpan. That thing is still a legend, and I hope to someday find a NIB or barely run version for my collection.
