I have attached the log file from a crash I experienced last week. If anyone can look at it and maybe gain some insight into what is happening I would be very grateful. (arm and crash happened between 11:45:30 and 11:45:50)
I armed the copter and spun it up without realizing anything was wrong. Once it got a few feet off the ground it suddenly flipped upside down and crashed. I have noticed reviewing the logs that motors 1,3,5 and motors 2,4,6 seems to be at very different values even though all I had done was increased the throttle. I tested this more after the crash and have noticed that if I leave the copter sitting on the ground with ~0.5 throttle, the motors initially spin at the same speed and then over time different motors speed way up and slow way down. My only question now is why is this happening?
