Last week, I had the chance to successfully fly my quad-copter for the first time. Unfortunately, the quad-copter crashed from around 30 m height. You can find here attached the log file. I still don't know what caused this crash. I hope that someone can help me out based on this file.
I am using Pixhawk as a flight controller. I was flying the quad-copter in loiter mode when suddenly it flipped and fell to the ground.
Thank you for your answers!
