Probably a bird attack.

Was flying my MP back toward my house this afternoon at about 175 feet--all of a sudden the video went sideways and it was like the gimbal got stuck then straightened out. Then all of a sudden the drone video was pointing down and sideways--it almost appeared the drone was in a short spin for about a split second. Then it straightened out/leveled out but I could see the props considerably. Was able to bring it back home ( was only about 400 feet away), but I didn't see a bird in the area. When I checked the video, it has a very slight glitch right before it stops recording which seems to correspond to the "hit". I uploaded the data to Airdata and there is an incident at that point (and the drone changes directions almost 70 degrees) but doesn't show any other anomalies. Checked the drone for any damage and don't see anything. Guess I got lucky on this one!

Gimbal reset it's pretty freaky if you have not had it happen before..

Thanks kidroc for the info. Yes--very freaky--that's why I suspected a bird.
