Steve, This of course is strictly a prototype. The pylons that the motors sit on will be much wider and slightly taller. The motors will be stuck on top via metal mounts and simply painted red to match the pylons. I am planning to use slightly larger motors than the 280`s pictured, and the props will be spaced away from the motors by extended adaptor. see the " help I want to build a hovercraft thread for extra info ! Shouldnt be expensive……..Ashley
