Is anyone interested in analyzing my recent log? I have sent it to 3DR and hope to hear from them soon. I flew Sunday and had a major issue. I flew with my GoPro mounted to the nose. Right from the start it seemed to really strain to get it the air and the throttle became really unresponsive. I could not make it gain or lose elevation, it moved on its own, or very delayed from what I did. As soon as I realized ( 15 seconds in ) that it was having issues I spent the ext 2 minutes trying to get it on the ground. It went up and down erractically, very scary... finally got it down and shut it down instantly. Any help would be greatly appreciated...fyi the battery was full and I had 11 gps.
