Having read through this thread, this is all too similar to what happened to me last night. I apologize if it’s more appropriate to start a new thread, but because of the similarities I thought I would reply here.
After 25 hours of flight time and hundreds of flight with no issue, i've started to have issues in the last month. Mainly loosing satellite signal for what seems like no reason. Last night, after flying in an open field with concrete grain elevators near it, a place i've flown many many times, the drone went rogue. It all of a sudden picked up speed and flew to the right and crashed into one of the grain elevators a couple hundred feet away. The last recorded speed was 52MPH without any help from the controller. The wind was around 5MPH, if that. Unfortunately, I don't think i'll be able to recover the data off the aircraft since its in pretty rough shape and the camera mount is no longer attached.
I do have a capture of the DJI app(sorry for the overlay) that shows around the 3:42 mark I loose satellite signal at 177feet while barely moving, maybe 2mph. The drone then immediately begins to take off on it’s own and picks up enough speed to make it all the way to at least 52mph, which was the last recorded speed before it went crashing into the wall of a grain elevator.
Although it did say satellite signal loss, healthy drones shows no issue with GPS. At crash time there was 15+ satellites.
This isn’t the first time i’ve experienced issues, a couple weeks ago I also had a similar issue. When loosing signal the gimbal dropped abruptly and the aircraft tilted. I was able to recover and finish out the flight without issue. Here is video with overlayed data:
Related or not, here is a video of the drone taking off on it’s own while sitting on the ground with no controller help.
Curious to hear anyones thoughts!
