Ok, so hopefully someone can help me pinpoint my problem. I was flying my phantom this weekend and I had two intermittent problems that occurred. I think it may be a motor issue but I am hoping for confirmation of this. I was flying and I tried to make a left hand turn. When I did so the entire left side of the quad dipped down. I stopped turning immediately and it recovered. I did this on a few occasions and it worked fine most of the time. Sometimes it would dip however and usually it would do it a few times before returning to normal. The other issue was when I was trying to bring the phantom back down. I had gotten my shot and I wanted to bring it back. When I tried to reverse the phantom it held steady and began to descend. This is at only 3 minutes or so of flight on this particular pack. When I released the directional stick it started to drop faster and go forward. I pulled back again and it stopped its forward flight but would not go backwards. It continued to drop accelerating as it went down. Didn't do any damage when it landed but I am concerned about taking it out again. Any input would be appreciated. Thanks and have a great day!
