And speaking of fast gliders, on the same day and a few miles to the southwest at Bird Springs Pass, a new dynamic soaring speed record of 545 MPH was set with a radio controlled glider!

Go to the 3rd page of comments for a video.

They had 80 mph winds at ridgetop.

5Z

It's a very technically competent group of people. I'm sure the flight wasn't gone into without appropriate considerations of the flight limitations. I was a bit surprised they chose to tow into the wave rather than use the jet engine for launch.

At this point it's up to the Duckhawk V to better the record, although the pilot workload is pretty high and having a multi-seater is an advantage.
