I just went to the site:
http://www.crazyplanesrc.com/ and it worked OK for me.
That said, it's a bit of a Crazy Site to go along with the Crazy Ball! There are a number of pages not yet populated yet, etc. By now, having bought two CB kits there, that I know which places to click on, etc. It takes several clicks on CB photos to get you to the page that has a Place in Shopping Cart link.
Yes, he's still selling kits. I recently received my second one.
