After reading a number of threads on this forum regarding the Atti mode, I've come to the painful conclusion that I need to learn how to fly my bird in this fickle mode. I've only had my P3S for a month with 18 flights and both of my crashes occured when the RC suddenly switched from PGPS to Atti. I guess this happens when you lose GPS or maybe a bad compass calibration. In any case, my quad drifted with complete indifference to my efforts to bring her home. So my question - how do I practice Atti without injuring my bird?
