Mainly I have been using APM boards but have just decided to try an Pixhawk and had a couple bad crashes so hopefully someone can hep me out with the logs to work out what went wrong.
Its a quadcopter setup and I have ran around 6 full batteries through it before this happened.
Was flying around in stab mode and it was fine when all of a sudden it just drops from the sky spinning. Then around half way down it picks it self level and starts to RTL. Thats when I switch it back to stab mode and it drops from the sky again into the ground.
See logs below. Its throwing up a few errors but unsure how they all link and what was the original problem.
