I'm brand new to RC and drone and just built my 1st drone, a 3D Robotic QuadCopter. VERY COOL! Unfortunately it crashed. I noticed that one of the motors would stop suddenly and the arm would dip, then recover. Did this about ten times over the three flights. Finally did it while in loiter mode while close to the ground, crashed and broke the prop :(.
It was hard for me to tell orientation, so I could not tell what motor was stopping. I'm hoping one of you experts out there can look at the log file and share your expertise. To me it looks like both roll and pitch went high which I think means the right rear motor dipped (running in X mode).
So, my two questions are:
- Which motor is stalling?
- What can be causing this?
- What troubleshooting steps can I take to confirm failure mode.
