RU-vid has been throwing dynamic soaring videos at me for a week or so and I finally watched Spencer Lisenby’s talk about the physics, aerodynamics and evolution of dynamic soaring. I had never heard of this and now I can’t get enough. The extremes, edges, and highest levels of nearly any pursuit can be fascinating.
Interesting that a rather small leeward gully provides so much DS power. Of course, the windward slope soaring look great at this location, too, and the foliage a good landing pad.
This is new to me and it's interesting. Is there a motor on it (I am hard of hearing)? Seems not because it's a glider. How does it work? I am guessing that you have to angle it into the wind in a certain way to make it go fast?
Tail end dynamic soaring stance I got a lot of energy that way but I crashed 4 times Mine was EPP you Got a lot of Confidence to do tail veiw DS in with a me olded glider I wonder if that glider is still in 1 pc
no - he switched from slope soaring (windward side of the hill) to dynamic soaring (leeward side of the hill) here's a good video about dynamic soaring ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nv7-YM4wno8.html
Then he reverses directions so he's looking at it taill first... I don't know what's bigger that plane or his balls made of carbon fiber..... Tail end view is tough...
If the plane crashes into the building, the flyer will have to pay a lot for damages to the building. It is not good place to fly. Why does he choose such a olace to fly? Whee is this place?
Well, maybe if he got up to 200 mph or more and the wings broke off cleanly when the model was pointed uphill and upwind. But I think those buildings are further away than they look. I suspect an airplane flying over the town would be a greater hazard.
John this hobby is not for you. You should go walk your dog, keep it leashed otherwise it could damage someone and then you will have to pay a lot for damages
