Was filming an extreme Jeeper going up a near-impossible obstacle in the hills above Calico, CA.. I was about 500 yards away and did not judge the distance to the canyon wall behind the bird and drifted right into it.. The P3 is in one piece and other than broken props and a slightly bend camera mount-arm seems to be ok.. but havn't flight-tested it yet.. Had a heck of a time being able to read the video-file but was finally able to get it repaired/readable.
