I recently returned from the Himalayas where I took my Mavic Pro up to 18000 feet. The only issue was a cold warning on the battery and reduced flight time because of it. An ND32 filter worked well. I’m returning next year and want to take the drone up to 21000 feet. Has anyone done this? Would a Mavic Pro 2 or Phanton 4 be better? Thoughts.
Sorry I took so long guys. Here is the Vimeo link to some of the footage I took. I dropped the resolution down, but was short in 2k.https://goo.gl/fRqLG3
