      This was a bit expensive because it uses K’Nex and a full length of 28 mm diameter tube. It did go quite well though.

      I like these ones, but if you are staying on the cheap side a groups of Yr10 pupils had the idea to stick two metal bars between the axles in an attempt to stop the axles from wobbling and I think it worked as the car went quite straight! It also added a bit of weight, which I think helps stabilizing the car too. It might lose a bit of speed though.
