Man...confidence level going down. I built a Y6 hoping for redundancy in case I lose a prop (last crash) or motor/ESC. I did have one strange occurrence while my craft was in RTH mode. It was windy and my Y6 yawed 45 degrees to the left. It still tracked straight home and later corrected the nose orientation. Reading about Flips of Death etc. made me wonder if it was a motor shutting down under the firmware or some kind of glitch that would have resulted in a crash if my craft was not a Y6. This happened on my second flight after building my Y6. I haven't had any similar problems since the last episode. This is with the old style GPS.
