Remove Sidebar on Custom Post Type

Hi,

I have created a custom post type but I don't wish to display a sidebar. Is it possible to remove it using the CustomPress configuration settings? Do I need to add an additional plugin such as Custom Sidebars?

Here is a link to a page where I would like to remove the sidebar
