Top-end parts can produce over a 10:1 thrust to weight ratio on performance drones at sea level. I would expect that's still enough to at least hover at the summit of Everest, and if not with the exact same specs, then with larger-than-sea-level-optimal propeller.
- orangepurple 4y agoThe batteries required to get up that far would make a 10:1 thrust to weight ratio difficult to attain if starting from low elevation. Plus Everest has strong wind shear and cold temps, both of which are extremely taxing on batteries. That said, this guy flew his drone to 40,900 feet from the ground in the wintertime: https://www.youtube.com/watch?v=k6QL0VjqYgI&t=0s https://www.youtube.com/watch?v=k6QL0VjqYgI&t=0s
- diimdeep 4y agoThis was almost 4 years ago, I bet that today someone could fly even higher. > The flight took place on January 3, 2019, near the Strezhevoy city, Tomsk Region, RUSSIA. (Western Siberia). My goal was to overcome the record height for rotary-winged machines (According to Wikipedia: June 21, 1972, the French pilot Jean Bulet raised the Aérospatiale SA.315B Lama helicopter to a height of 12,442 meters), which was completely possible. My drone reached a height of 12,467 meters from ground level as measured by GPS and 12,925 meters from ground level as measured by a barometer, which is standard for aviation.
