YoumiTrip - Trek to the 3rd largest cave in the world

[youmdingding]

Still in Vietnam, I went to the Hang En cave in Phong Nha-Ke Bang National Park, the 3rd largest cave in the world. And I got to fly my drone in a cave for the first time! Have you guys flown in similar places before like caves, or canyons?
Hope you enjoy the video

Flying in the cave would be a good use of Phantom3

Yep, you do an amazing job.
