James F Scott’s 1910 smaller craft looked like a helicopter, but wasn’t. It consisted of an open structure bearing two V-frames on which 16 discs were mounted in fore and aft V-frames. The 8′ diameter disks were built of radially ribbed fabric, like umbrellas. There was no drive-shafting or other driving mechanisms for the disks, but a 40hp water-cooled engine drove a pusher propeller. Apparently, the disks were supposed to produce some form of lift. It is not known if the contraption was ever flown.
