The vpp looks great! You have to see the video of it at hobby-lobby.com. In the future we will probably see a full scale edge with a vpp prop.
Too bad none of us will be alive to see that, bc right now we are having trouble producing VPP props that can handle over 10 oz of thrust. Much less a 14,000 LB airplane (not sure how much a full scale aerobatic plane weighs though.)
