WOW! That's crazy.
I agree with everyone else. Looks like a bird strike! This was certainty, not anything to do with Litchi. I use Litchi exclusively and have never had an issue. It just simply works.
I will share with you I had a similar experience, but not a complete flip like yours. A short time ago I was flying a Litchi mission, one I routinely fly, and when I looked at the video after the fact, I saw something shocking. Towards the end of a 14 minute flight while it was on the way home I see my phantom take a dive to the right and the recover just a few seconds later, somewhat like yours did. I can't 100% rule out a bird, but I was 400 feet in the air and don't really think so. Here is what happened though the next day. I took my phantom out to fly and now I get this "ESC-error" and my bird is dead! After 5-6 times trying to start the motors I give up, not really knowing what has happened. I didn't crash and just flew it the night before. The next day I try one more time and now all motor fire up except one. Ah, there's the problem...bad motor? I talked with DJI support and they told me either bad motor or bad ESC, in which I would need a new main board. I gave that motor a turn and it did feel rough to turn. So, I bought 4-new motor since they are not very expensive, and I figure it is good insurance. My phantom is 1 1/2 years old and I fly it a lot, so I don't mind spend a few bucks on it for sure. Anyway, after I swapped out the bad motor, I figured I'd see if all was good, and to my surprise I have the dreaded "ESC" error again. What! Do I really need a main board? Now to explain I just cut the wires in the middle coming from the main board instead of unsoldering off the board itself. That is what a lot of people suggest to do when replacing motors. Upon further inspection, I see one wire going to that motor looked suspicious right past the solder joint on the main board. Sure enough, the wire was broken under the insulation. I swapped that out with another new motor and soldered it directly to the main board which was a lot easier than others had suggested. My phantom fired right up with no error. I went ahead and installed the rest of the new motors and I have been up and flying for a couple weeks now without issue.
Looking back, I had a couple times where I also had the "Loose prop or missing propeller" error that I couldn't explain either. I bought it home and check the props and all were tight. I wonder now if I had that wire coming apart, but not totally broken and giving the ESC fits......never know I guess.
Sorry for the whole story here, but my point is I would have never guessed I had a broken wire. I am lucky to have made it home with mine. Just saying, it looks like yours took a hit, but if you don't think a bird was the issue, it might be worth taking the top shell off and looking at your connections closely. I may be way off base with this, but I know what my experience was. Just thought I would share for anyone that might find it helpful. |
