Product Description

This is most advanced and efficient rubber band propulsion system ever designed for propelling a rubber band powered vehicle. Doc Fizzix's rubber band propulsion system provides for a more uniform transfer of potential energy into kinetic energy while maximizes the total amount of energy available compared to more traditional rubber band propulsion methods. The secret to the pulley launch system is that it is designed to stretch the rubber band longitudinally instead of twist winding as is common with most other rubber band vehicles; our launch system will double the power output and double the torque of the system causing vehicles to "rocket" off the start line giving them an almost unfair advantage over the rest of the competition.

Also includes our "easy-wind" and "snag-free" string release system that will not tangle and/or snag on release for maximum performance, a technique developed exclusively by Doc Fizzix for mousetrap powered and rubber band powered racers. Our snag-free propulsion system is designed to release from the drive axle once the pulling force is spent in order to maximize the coasting distance.
