My 1/8th scale "Live Diesel" Long Island C420 in fabrication. The backbone is 2" x !" "C" channel, decking is 16g. sheet metal, edging is 1" x 1/8" flat bar. She's getting too heavy for me to lift on my own, about 150 pounds so far. Drive will be 24 volt electric motors on each truck. This will be painted in the World's Fair gray and orange sweep. I made the truck molds from wood and a a friend has cast them for me in aluminum, recycled from old lawn mowers and other scrap.
