Wow---that's what I was looking for all right--thanks so much. I think the wingspan on the Phoenix 1 was around 67". How much larger was the "3"? From the RCM article on the Phoenix 1, Don said overall the greater sweep helped the plane fly better under windy conditions, but all later versions of the Phoenix had less sweep. Do you know what the negatives of increased sweep are, and why he went to less sweep over time?

Again, thanks for the great reply, and looking forward to seeing you.
