THe Temple of Heaven Parachute Company of China used to make a single surface, flat rigged cargo canopy. It looked like on of our ram-air canopys with no top skin or ribs. I don't believe it was steerable. I have a brochure on it.
Oh, I almost forgot Jerry, the Pioneer copy of the Cloud was a Titan. I had one and thought the reason for the single tail was that they ran out of fabric.
