So i was flying at our hunting club the other weekend, i was following the drone on my atv and everything was going fine, i had to put another battery in it at one point and took off again, i proceeded back to our cabin and the battery was getting down to around 30 percent, i took off ahead of me and initiated a landing at our cabin, i was positioned about 400 yards away, as the drone was in landing mode and about 20 feet off the ground, i lost all video monitoring. I raced back to camp and was able to restablish a video feed, at this point the drone was flying crooked and it was reading a compass error had occured. i manually brought it in and landed (after much difficulty as the controls were not reacting properly) i touched down and the drone flipped over and the propellers wouldn't shut off. i had to shut the battery off to stop the motors. i pulled up the video file and found that when i lost signal with the drone, it turned to (go home) and flew directly into a tree causing a prop to break and hence why it was flying crooked, landed crooked (causing it to flip), and why there was a compass error?? My question is, whenever it is in "go home" mode isnt it supposed to use the sensors to tell if theres an object in front of it and fly over it? Luckily the only damage was 1 broken prop, i replaced them and the drone is flying normal again. I just want to know so in the future i can try and prevent things like this from happening again.
