Bill,
I was at the Southern Colorado regional in Colorado Springs. I didn't catch the final results because we left in the mid-afternoon, but at that time, first place got 2:19 on their first flight, but lost the ship on their second flight on top of a light fixture. I did not get to see this design. Second place was less than 20 seconds.
