As you can see in the video the skateboard handles GREAT! The 4WD really keeps the board going, and if the tires lose traction it drifts controllably with all 4 wheels spinning. Ok fine, sometimes it's "uncontrollable"... 

Special thanks to: My Dad for working on the wiring and pulling an all-nighter with me; to my Uncle Paul for letting me use his machine-shop; and my lovely girlfriend JuliAnn for filming this!
All I ever talk about now are Electric Skateboards, it's amazing I still have a girlfriend after all of my projects. It must drive her crazy. Haha.

Thanks.
