Hello everyone,
Yesterday morning I went hiking to a usual spot that I've visited a couple times and have flown my Spark without any issues. First take off was normal and I managed fly a few meters up and away. Whole flight probably lasted 3 min max. I brought it back and suddenly I got a warning that there was some magnetic interference. I decided to not risk it and went on my way to a less secluded area of the trail.
Second flight was a mess. Everything started up and all indicators were green, but then as it was taking off it started hovering erratically until it hit a plant. It didn't get that high and needless to say instead of hovering up in the same place as it went up like it usually does it moved to the side on its own and crashing. I checked for damages and eveything was intact. I tried again and got it slightly higher to take a sphere panoramic shot. Everything was going smooth until it started behaving erratically again. It started moving side to side a little bit at first, but then it looked like if I let it go any longer it would fly beyind my reach. Out of fear that this time it might lose control and fall down the side of the mountain I caught it and called it day.
When I got home I decided to test in the backyard to see if maybe up in the mountain the strong winds were making behave that way. To my surprise it started doing exactly the same thing as soon as it took off. It was going up and down on its own and then side to side. I tried landing it, but it wasn't responding to the controller and instead it was going down, lightly hitting the ground (had a landing accessory so it didn't hit the ground directly) and then up again. Once again, everything was green and there was no indication of any error. I recalibrated the compass once, tried flying with the same result, calibrated the compass again and no luck. I searched online and saw a few older threads of people with the same experiences. Unfortunately half of the threads ended in nobody knowing what's wrong and the other half with "I gave up, returned the spark and got a mavic".
Decided to try again after I calibrated the IMU and it did okay the first minute. Then it started behaving erratically again except now I am getting all 4 red lights which to my understanding is a critical error. I calibrated the compass, checked that every firmware is up to date on batteries, RC and drone using DJI Assistant and everything seems to be in order. Any help or tips? Spark was working flawlessly 3 months ago when I last used it on the exact same hiking trail.
