Don't need a motor to go really fast

[Hang 4]

Hard to see much in this video, but they set the world speed record for an RC glider. After reading the article, the flight was back in 2018.. but still pretty amazing.

I have been following Dynamic Soaring activity for a few years and it is no less extraordinary. I sometimes start to think, no, I don't believe it, it's just kids having a laugh on youtube, however I am sure it's all true.

I had not noticed this speed before. Thanks.

Here is a 1h video presentation by one of the DS aircraft designers/pilots.
