The North Carolina-based recruiter looks like he is giving hints to the team from the R.L. Turner High School's Math, Engineering, Technology & Science Academy in Carrollton, Texas. They are about to run the Pit Stop Challenge in which teams have to work together to drive their R/C cars a short distance, change tires and batteries then send the car back to the start-finish line. It is all about teamwork and some teams modify their cars in ways to make it go faster. For example, with a quick disconnect battery. Some choose hand tools while others choose power tools.
