So I went for a quick flight the other day, clear skies, mid 30's, good flying weather and since the leaves are off the trees I thought I'd check out the abandoned rail yard that I drive past often. I get up to about 100' and hover over a building and notice that the drone is drifting to the left, Hummmm, ok. I did some quick shots and flew to the far end of the yard. Now the drone is about 500 meters away and about 200' altitude. All of a sudden it takes a dive to 150' and back up to 225' all without my input. Just then I get a message on the screen saying "Main controller data error" So naturally I immediately fly it back to me. On the way it changing altitude on it's own.
After a few minutes I get it hovering above me and it's a fight to get it back down. I ended up cutting the motors at around 50' and letting it fall into a big sand pit. No damage at all. I brought it home and swapped batteries, calibrated the IMU and controller and hovered it for a while in my garage. It was obviously drifting even without a GPS signal so something is wacky.
Oddly enough it flew fine two days before, it was never crashed or landed hard. Air data didn't show anything out of the ordinary in the logs.
