I am going to build a custom skateboard that will go down hills very fast, yet turn well also. I took the trucks and wheels (roller-blade wheels) off of my street luge (only momentarily) and put them on a 2x4 that is slightly longer than a normal skateboard. Then, I screwed on the deck of the skateboard to the top of the 2x4. It is as simple as that. The new and improved is soon to come.
