i always move my videos from my SD card to my video folder so I always have plenty of space. I do a lot of wildlife video and today I had a once in a lifetime opportunity. I had been flying around for 5 minutes or so before I saw a big alligator on the bank of the bayou and I got in real close. I got to about 3 feet away and 4 feet above his head when he opened his mouth and hissed and lunged. I figured that may happen so I was ready to pull back on the stick as he did it. He then slid right into the bayou and was submerged for 30 seconds or so. I saw him pop his head up and I again got really close. When I did he dove under kicking his tail up in a huge splash which sprayed my bird a tiny bit. He did this twice more until I had to come in on low battery. I check my app to see how long I had been filming and I noticed it had stopped filming at 4 min! I missed all of it! I was so focused on video and keeping my Phantom just above the water that I didn't notice the SD card had gotten full!!! I now remember that after I had transferred the last group of videos to my library I got a phone call and got distracted and forgot to erase them. I'm so pissed! I was able to pop in another battery that only had about 30% on it along with a new SD And get one shot of him but he had gotten curious by then and just kind of floated there looking at me.
