Got more video today...could be faster, but not sure. I think that I am not going to go any faster with this prop as is. I am going to try and get numbers myself, but can MJD or Mike can help me out with a second opinion? Here is a link to some of today's flying. Pass at the end around 40 seconds was closest to the camera (and my face) and seems the fastest, but the one before it around 23 seconds also seems fast. Thanks!
