I was flying my drone earlier today. It was sitting at a hover taking pictures, when suddenly it turned 90 degrees and flew off about 80ft. Then, it turned around and flew back close to where it flew away from. Luckily I had a flyaway failsafe that brought it back to its home position.
Looking through my logs I don’t see any excessive vibration, but I do see an increase in the norm of the magnetic field right at the time of the “flyway”. It does not correlate with the thrust, but could it still be EMI?
