Wasn't quite sure what you meant by "dynamic soaring"
- large, motorless R/C model gliders on those windy western hillsides!
I went to a local (flat field) meet up years ago for those things - launched by a wench slingshot thingie. They weren't doing anywhere near those
speeds. But when one passed overhead, you KNEW it! :o Those things could kill you!
(You can see the plane much better in this nearer, slower speed one than in the distant, faster shots.)
