Earth shattering secrets for building record setting and winning mousetrap cars and racers. Here you will find all the latest and greatest untold construction secrets so you can build your very own mousetrap vehicle.

Mousetrap Vehicle Propulsion Systems

Before you build a mousetrap powered car you need to understand the basic propulsion systems. This article will show you how to use a mouse trap to propel a vehicle.

How to Make an Axle Hook

The most common way to propel a mousetrap car is to attach one end of a string to a mouse trap's snapper arm and the other end of the string to an axle hook.

Attaching a Lever Arm

For any mousetrap racer the gearing and pulling force are controlled by the length of the lever arm. This article will show you how to attach a new lever arm.

How to Make a Loop Knot

It is important for the pulling string to have a correctly tied loop knot in order release itself from the axle hook or the mouse trap vehicle will come to an instant stop.

How to Attach The Mousetrap

Stop gluing the mousetrap to the frame, the problem with gluing is that you cannot make critical changes or adjustments to the mouse trap after any testing.

How to Change The Gearing

Gearing is how you control the acceleration and/or the travel distance of a mouse trap car. Gearing can be used to increase the torque and increase the acceleration.

How to Adjust the Pulling Force

The trick to building a record-setting long distance racer is to decrease the mousetrap's pulling force so that it's energy is used over the longest possible distance.

Decreasing Friction

Controlling friction is the number one secret behind building a winning and record-setting mousetrap powered vehicle. Learn how to decrease and eliminate friction.

Bushing Systems

If you cannot use ball bearings then a good bushing system can be used to decrease the amount of surface friction at the axle points and maximize performance.

Make a Super Long Lever Arm

Longer lever arms have a greater pulling distance but tend to bend under load and waste energy. Learn how to make a super long lever arm that will not bend.

How to add Adjustable Steering

One of the problems with mouse trap cars is getting them to go straight down a long narrow hallway. The article will show you how to add adjustable steering.

Using CD/DVD Wheels

CDs and DVDs make great wheels because they can slice through the air with very little resistance but the biggest problem is how to attach them to an axle system.

How to Increase Traction

Acceleration depends on the amount of grip or traction your vehicles wheels have on the floor, learn how to increase traction and acceleration with less energy loss.

Decrease Rotational Inertia

It does not matter if you are building a long-distance traveler or a speed-trap racer, decreasing rotational inertia is going to make a big difference in performance.

Frame Construction

Frames need to be strong but yet as light-weight as possible, this article will help you pick the right materials to use for building your mouse trap vehicle's frame.

How to Make a Super Large Big-Wheel

With all long-distance traveling mousetrap cars, the larger the drive wheel the greater the travel distance per each wrap of string pulled from the drive axle.

How to Make a Braking System

This article will show you how to make an adjustable and accurate braking system that can be attached to just about any mouse trap powered vehicle.

How to Make a Reversible Vehicle

Going forward and then back is as simple as how you wind the string around the drive axle. this article will show you how to make a reversible mousetrap vehicle.
