I searched the Q&A, the forums and several mfg tech specs and have not really found the answer so forgive me if I missed it. I also called DJI and frankly their tech support folks just read off the same spec sheet I could find on the web. So no definitive answer there. I am at located at 9200 ft above sea level and am trying to determine if quadcopter drones will actually fly up here. I expect max height of interest would be approximately 200 feet above ground level. So has anyone tried to fly at these altitudes? I know most helicopters have difficulty with lift at 10000 feet so that is why I am asking. Am I just looking at reduced payloads or will they just not fly well at all. I'd like to know before I purchase anything. Thank you!
Depending upon the UAV you may, or may not be able to fly at that altitude. Less dense air up that high. But, others have successfully been able to make just about any fly by changing out motors / propellers, modifying the propellers (on ones that have to use the one that came with it). You need to either increase motor RPM, increase propeller pitch / diameter, or do both.
DJI claims their P3 models can handle 6,000 meters. Many users have flown them at typical USA mountain heights (7,000 to 9,000 ft). http://www.dji.com/product/phantom-3/spec
