Tonight was a rough night. Got home from work late and decided to do some flying with my Phantom 3 Pro. First flight went off with no problems. I landed and had to change batteries and grab a snack. While eating, I saw that DJI released an update to the Go App so I updated. After the update was complete, I grabbed a fresh battery and went back out for another flight. About 5 minutes into the flight, the App froze. I forced it to close and restarted it. About 10 seconds after the app reconnected, the drone started to spin. I hit the "record' button and tried to gain control with not much success. The drone stayed on after hitting to ground and I was able to track it down with relative ease. Much to my surprise, the drone appeared to be in good shape. The only obvious damage was a broken blade. I took it back home and extracted the flight records/video. I was initially thinking that something went wrong with the compass. I replaced all of the blades, rebooted the drone and recalibrated everything. Everything appeared to be in good working order. I took it off and had it hover for a few minutes at 10-15 ft. It hovered fine and responded appropriately to all commands. I took it up to 175 feet and started to fly. About 90 seconds into the flight it started spinning out of control and crashed again. Here is the Healthy Drone log and video from the first crash http://healthydrones.com/main?share=Mjg1Ng https://www.youtube.com/watch?v=b7vKsVvxENw
And here is the log from the second crash http://healthydrones.com/main?share=Mjg1Nw Normally, I'm the first to say that any given crash is caused by pilot error. I know I did everything right on both of these flights. It's very suspicious that these incidents happened after updating the app, especially when I had successful flights right before the update. I do not recommend updating to the newest version of DJI Go until this can be investigated further.
