Description:

Lock-Tight is the most advanced and the easiest to operate braking system available. Lock-Tight has a wing-nut that travels along a threaded axle and then wedges itself against the frame causing the racer to come to an instant stop. Lock-Tight 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, Lock-Tight 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 Lock-Tight a winner.

Features:

  • Top secret braking system
  • High-grip tire treads
  • Light-weight balsa wood
  • Brass tubing axles
  • 12-inch brass lever arm
  • Pre-cut and pre-drilled
  • Doc Fizzix's easy-wind, snag-free propulsion system
The Lock-Tight can be assembled in less than 45 minutes for most first time builders and when finished can be set to travel and stop between 1-45 meters. Lock-Tight comes with a 12-inch lever arm making Lock-Tight a good long-distance vehicle without the need for adjusting the lever arm length once assembled.

How it works:

Lock-Tight's braking system uses a special wing-nut that travels along a threaded axle until it lock tight against the frame of the vehicle causing the Lock-Tight to come to an instant stop. Setting the braking system is simple and easy: just place Lock-Tight at the finish line with the wing nut in the lock position, roll the vehicle back to the start line, and now you are ready for racing. Rolling Lock-Tight from the finish line to the start line sets the wing-nut in the exact position needed. Lock-Tight also comes with two rubber treads that are designed to increase the stopping traction helping the racer to come to a stop without skidding.



As with all our top mousetrap racer kits, Lock-Tight 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.
