This is my dragster. It is driven by 2 xl motors, geared up with a 40 tooth to 8 tooth gear combination.
It has a pair of tiny wheels on the back of the battery box with a soft shock absorber to prevent the battery box from scraping against the ground. It has a top speed of 5.5 miles per hour. Overall this model was strictly made for speed so it only took about 1/2 an hour to build.
