In preparation for my travels to Brazil and Argentina next week, I did a high altitude test with my drone.  Pictured above is a portion of the Concord Country Club golf course which is across the street from our home.  I wanted to determine the amount of battery needed to reach and return from max altitude so I can estimate how many flights I can get on a single battery.   I will be returning to Mount Fitz Roy with Nico and one of my soccer teammates. On my last visit, I did not come away with a single clean image as the peaks are shrouded in clouds more often than not.  If I see an opening in the clouds I plan to stop, no matter where we are on the climb, and put the drone up immediately.  Check back in two weeks to see if I was successful in capturing a decent image.
