Double Trouble is a twin-powered mousetrap racer that delivers twice the pulling power and twice the fun. Double-Trouble is the exact same kit as our top selling Basic Kit but comes with two mouse traps. Double Trouble can be used for any contest that allows two mouse traps on one racer or it can be built with just one mousetrap. Double-Trouble comes ready-to-assemble with pre-cut and pre-drilled parts so you can be ready for action and racing on the same day. As with all our kits, Double-Trouble comes with 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 Double-Trouble a winner.


  • Light-weight balsa wood
  • Brass tubing axles
  • 12-inch brass lever arm
  • Pre-cut and pre-drilled
  • Low inertia DVD layer wheels
  • Doc Fizzix's easy-wind, snag-free propulsion system
Double Trouble can be assembled in less than 45 minutes for most first time builders and when finished it will travel from 50-80 meters (when used with two mousetraps). Double Trouble comes with a 12-inch lever arm making Double Trouble a good long-distance vehicle without the need for adjusting the lever arm length once assembled. Double Trouble can also be built as a single mousetrap powered vehicle giving the builder and extra mousetrap as a spare.

As with all our top mousetrap racer kits, Double Trouble includes our "easy-to-wind" and "snag-free " string release system that will not tangle or snag for increased performance, a technique developed exclusively by Doc Fizzix.
