I have the same problem with my Mantis and I emailed Yuneec and still waiting for their answer....it is annoying to have that issue everytime you do a video.....
While on vacation, I decided to take my Mantis over the coast to take some awesome footage "beach" side of Caribbean in Puerto Rico. Unfolded the quad and when I was ready to turn motors for flight, this message popped up. Note: I was near the airport and I'm very familiar with FAA rules/...
As you get to know your drone, more options you will find under photo options to choose from and edit as you capture every moment during airborne.
Footage are in original, low, high ultra high quality as well as non edited and edited. Enjoy.
