Rubber Band Racers 9-60V 20A DC Motor Speed Controller Always remove batteries during extendedRubber Band Racers Rubber Band Racers are mechanical toy vehicles powered by elastic potential energy stored in wound rubber bands, designed to demonstrate fundamental principles of energy conversion and motion mechanics. Educational institutions, STEM program facilitators, and robotics enthusiasts use these devices to teach kinetic energy transfer, gear ratios, and mechanical advantage in an interactive, hands on format. These racers solve the
