So just came back from a gruesome 26 miles roundtrip mountain hike to havasupai falls and took my MA with me. Flew it several times to get some nice shots and came back to find nothing recorded in the sd card! Luckily it was stored in internal memory...phew, video to come. Oh and btw before i get drone copped, all flights were not near anyone or the campgrounds and were planned. Didnt even need more than one battery to film every waterfall so planning your flights beforehand does wonders.
