My name is Joan, i'm from barcelona, Spain.
My project is to improve the aerodynamics of my soapbox, gravity racer or carretons (which it is the name in Catalan), As you may know , these vehicles are powered only by gravity, and one of the factors which limit its speed is the aerodynamic drag, and many of the ideas explained in this forum apply to my project.

-determine the new cd
-calculate the improvement, and test how effective is the improvement
the actual soap box:
