In order to make the 6″ PVC work, I added to the design. As illustrated in the pictures, I used steel garden edging stakes with holes drilled in them to add to the length of my blades. The most important part of this though, is the fact that I bent the stakes so the blades are sitting at about a 30-45 degree angle to the hub, allowing the wind to push them sideways and around rather than back, putting less strain on the guy wires and foundation, and producing more electricity.
