For sale is a used HPI Nitro RS-4 2 Upgraded with an Epic .18 engine. engine has about 5 tanks of 33% trough it and runs great. Car is in decent shape. one of the body mounts is broke, and the bottom is beat up like most are. streets in my hood are too rough for a touring car. will include original .15 engine if you want it. just add your tx/rx, and gas. car is single speed but still pretty fast. Slicks pictured are sold..
