Nick Paparesta asked if there was a substitute for the plastic conduit I use for the chassis in my first mousetrap car video. The answer is yes, if you search through my car videos I use quite a variety of materials for the chassis. Here are a few ideas – curtain track (plastic or metal), bamboo flower canes, cardboard. I probably use cardboard most often now as it is freely available for most people.
Another question I am often asked is what to do if there is not enough power to turn the wheels. Although this car moves OK as designed I demonstrate increasing the diameter of the back axle to increase the leverage effect, by wrapping some cardboard round it. This makes the car accelerate faster. The disadvantage is it might reduce the total distance the car can travel as it takes more line for each revolution of the axle, however as the car accelerates faster it might achieve a greater velocity and allow it to freewheel further at the end of the run. There will be an ideal combination which will give the best overall performance and only experimentation will find this.
