- This rubber band racer includes Doc Fizzix's top secret braking system that can be set for any distance
- Perfect rubber band vehicle kit for beginners and seasoned veterans alike. Designed and engineered for success by a former award winning Texas physics teacher. Comes ready-to-assemble with pre-cut and pre-drilled lightweight balsa wood.
- This rubber band car kit comes with light-weight brass tubing axles that spin with less friction for increase speed and distance, and do not warp like wood dowels, for a smoother ride without wobble.
- Includes Doc Fizzix's flexible rubber CD/DVD wheel spacers that are designed to act as shock absorbers to damper small bumps and imperfections in the road surface providing for a smoother ride that will increase both the speed and distance of your vehicle project.
- This kit features Doc Fizzix's easy-wind, snag-free propulsion system designed specifically for mousetrap and rubber band racers
- Also inlcused Doc Fizzix’s pulley launch system for a rocket start and a more efficient storing of energy
- As an added bonus, this rubber band racer kit includes traction tire treads to give this racer a rocket start and a perfect stops every time
DESCRIPTION:
Stop-Action is one of our most advanced and the easiest to operate rubber band racer kit that includes a braking system. The Stop-Action Kit has a wing-nut that travels along a threaded axle and then wedges itself against the frame causing the rubber band racer to come to an instant stop. The Stop-Action Kit comes ready-to-assemble with pre-cut and pre-drilled parts so you can be ready for action and racing on the same day. Includes step-by-step instructions that are filled with tons of top secret performance tips and tricks that have been developed exclusively by Doc Fizzix so that you will have all the information you need to make The Stop-Action rubber band racer a winner.
The Stop-Action rubber band racer uses our all new revolutionary pulley launch system that is designed to maximized the potential energy of a stretched rubber band into kinetic energy with almost zero loss of energy. The secret to the pulley launch system is that it is designed to stretches the rubber band instead of winding it as is common with other rubber band vehicles; our launch system will double the power output and double the torque of the system causing the Stop-Action racer to "rocket" off the start line with an almost unfair advantage.
TRAVEL DISTANCE:
The Stop-Action rubber band racer can be assembled in less than 45 minutes for most first time builders and can be set to travel and stop between 1-45 meters. (the locking system will work between 1-10 meters).
