Act IV: Building a test track

 

In Act IV, we present detailed step-by-step instructions on how to build a 2-lane test track for testing your car prior to the competition, and for selecting an entry car (if you make more than 1 car). This track would not win a beauty contest, but it works very well for testing your cars. The nice thing about this track is that it can be made out of inexpensive scrap lumber. Further, it does not need an electronic timer to serve its purpose.
