I was flying in my yard and deceided to try the Course Lock on my P3S. Shortly after switching from P to F mode I applied the Course Lock mode. I was at approx. 80 feet in the air just on the other side of the neighbors house when the a/c started violently shuttering and losing altitude. I dropped the controller and was going to see when the bird landed and it appeared just above the house where it crashed. I switched back to P mode and returned and landed safely. After reviewing the SD card I saw that it hit the ground (grass) and before I could get to the a/c it was back in the air hovering just above the roof of the house. This is the second time it has done this and I believe I was in Course Lock both times.
