MOUSETRAP POWERED CARS

A complete "do-it-yourself", mousetrap, rubber band, balloon, and/or STEM vehicle project rolling chassis. Comes with everything you need to get your STEM vehicle project rolling in the right direction. All the hard-to-find parts, pieces, and components in one complete package, you just have to add your own power source. Includes everything you need to make your STEM vehicle project a winner:

• Lightweight Balsa Wood, pre-cut and pre-drilled frame
• Ultra-thin Low Inertia DVD Layer Wheels
• Flexible Shock Absorbing Rubber CD/DVD Inserts
• lightweight, 3/16" inch brass tubing axles
• "easy-wind" and "snag-free" string release system
• Thrust washers for reduced frictions.
• Top secret, step-by-step instruction guide

Includes our ultra-thin, low inertia wheels are the same diameter as a standard CD/DVD but only half the thickness and only half the rotational inertia. Half the rotational inertia means your vehicle will have a greater acceleration off the line and a greater travel distance compared to a similar mousetrap/rubber band powered racer using standard thickness CDs/DVDs as wheels. Our Ultra-thin, Low Inertia Wheels have been proven to increase a vehicles travel distance from 5-10 meters compared to the same vehicle using standard thickness CD/DVD wheels.

Includes our flexible rubber CD/DVD inserts that are designed to fit perfectly inside any standard CD/DVD so that it can then be fit onto an axle. CD/DVD inserts are made from a flexible rubber that is also engineered to act as a shock absorber to help damper small bumps and imperfections providing for a smoother ride, with less wasted energy.

Includes our lightweight, 3/16" inch diameter brass tubing axles that spin with less friction and will not warp like wood dowels used by many of our competitors in their kits. Our Ultra-thin, Low Inertia Wheels and Axle setup will have your vehicle traveling smoother with less wobble and less wasted energy for an increase in both speed and travel distance.

And finally, includes our "easy-wind" and "snag-free" string release system that will not tangle and/or snag on release for increased performance, a technique developed exclusively by Doc Fizzix for mousetrap and rubber band powered racers.

Top Highlights:

• Designed and engineered for your success. Comes ready-to-assemble with pre-cut and pre-drilled lightweight balsa wood frame. Just add your own power source.
• Flexible design options, can be assembled in a variety of different ways making it the perfect all purpose project package for just about any type of STEM vehicle challenge you can dream up.
• Includes Doc Fizzix’s Ultra thin, low-inertia wheels that are half the thickness of a normal CD/DVD and have only half the rotational inertia. Less rotational inertia means your mousetrap car will travel further and faster when compared to a similar vehicle using normal thickness CD wheel.
• Comes with lightweight, 3/16" inch diameter brass tubing axles that spin freely with less friction for an increase in both speed and distance. Brass tubing axles do not warp like wooden dowels and provide for a much smoother ride without wobble.
• Comes with Doc Fizzix's flexible rubber CD/DVD wheel spacers that are designed to act as tiny shock absorbers to damper small bumps and imperfections on the floor's surface providing for a smoother ride with an increase in both the speed and distance.
• Features Doc Fizzix's "easy-wind", "snag-free" propulsion system designed specifically for mousetrap and rubber band powered racers.
• Comes with our complete step-by-step instruction guide that is written the for the visual learner filled with tons of top secret performance tips and tricks.
• All our products are 100% made in the U.S.A by Doc Fizzix in Spicewood, TX.

Includes the following:

• 2x - Pre-drilled frame rails
• 1x - frame dektop
• 6x - Low inertia DVD layer wheels
• 2x - 4.5 inch Brass tubing axles
• 4x - thrust washers
• 4x - CD/DVD Wheel Inserts
• 18" inches of Kevlar sting
• Doc Fizzix's easy-wind, snag-free propulsion system
• Step-by-step plans with performance tips and tricks

*Kits require assembly, actual results will vary and depends on the constructions skills of the builder, glue and tools not included.

Easy-wind, snag-free propulsion system

As with all our top racer kits, Rolling Chassis Kit 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 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.

Ultra-thin, low-inertia wheels and Axle System

One of the design secrets that make Rolling Chassis Kit a guaranteed winner is it's low inertia wheels and axle system. Rolling Chassis Kit includes our exclusive ultra-thin, low inertia, DVD layer wheels that are the same diameter as a normal CD/DVD but with only half the thickness. Because these wheels are only half the thickness of a normal CD/DVD they have only half the rotational inertia, half the rotational inertia means that your vehicle will have a greater acceleration off the line, less friction, and a much greater travel distance compared to a similar mousetrap car that is using normal thickness CDs/DVDs.

Our low-inertia wheel and axle system includes our lightweight, 3/16" inch diameter brass tubing axles that spin with less friction than wooden dowels for an increase in both the speed and the travel distance of your vehicle. Brass-tubing will not warp like wood dowels used by many of our competitors in their kits so our Rolling Chassis Kit will travel smoother, with less wobble, and less wasted energy for an increase in both speed and travel distance.

Key components to our low-inertia wheel and axle system

• Ultra-thin, Low-Inertia DVD layer wheels.
• lightweight Brass Tubbing Axles.
• Flexible Shock Absorbing Rubber CD/DVD Inserts.
• Thrust washers for reduced frictions.

Flexible Rubber CD/DVD Wheel Spacers

Lets face it, even the smoothest hallways and surfaces still have some small imperfections and bumps that can steal energy from a moving vehicle causing a decrease in performance. Our CD/DVD inserts are manufactured from a flexible rubber that is engineered and designed to act as tiny shock absorbers to damper small bumps and imperfections along the road surface providing for a smoother ride with less wasted energy causing an increase in both the speed and travel distance of your STEM vehicle project. Our CD/DVD Inserts are designed to fit perfectly inside any standard sized CD/DVD opening in order to converts the hole size down to fit a 3/16" inch diameter axle.

Easy to Follow, Step-by-Step Instructions

The Rolling Chassis Kit comes with our complete step-by-step instruction guide that is written the for the visual learner filled with tons of top secret performance tips and tricks that have been developed, tested, and perfected exclusively by Doc Fizzix, with over 30 years of experience, so you will have all the information you need to make your mousetrap vehicle project a success. Our easy to follow, step-by-step instructions are filled images and diagrams designed to eliminate the guess work. You will feel confident and feel like a professional builder as you follow our detailed step-by-step instructions.
