In my high school electronics class circa 2006, we built motorized cars using a gatorade bottle and drag raced them head to head. I added a spur gear, pinion gear, esc and receiver from a Duratrax Evader to mine along with glueing a rubber band to the plastic wheels we were provided Not only did I have the fastest gatorade car but I could also stop and reverse it unlike the other entries

it didn't look too far off from this
