Experience the Thrill of Dynamic Soaring for Extreme RC Glider Speeds

[Flyboy]

I'd heard about this concept for years, and I remember seeing some videos a long time ago of some frankly ridiculous speeds coming from it, but wow. They're pushing RC gliders to speeds where swept wings are starting to become viable. All from wind shear at a hilltop.

Brown pelicans use the principle everyday here in Florida, not for speed but for energy saving:

Yeah, we had a thread a couple years ago by @anorlunda that started with that same video. Pretty amazing stuff.
