Hey, First of all I'm pretty new to this, expect filming. I may be stupid, but i can't figure it out. I flown 7 hours on my phantom 3 proffesional in gps mode, and it served me well! I was curious to try atti mode, but it's kinda annoying? It just keeps drifting away in one direction. Example, if i move forward and i let go my controls, it stops and slows down and moves backwards. If i go sideways and i let go my controls the same happens. It just keeps getting back in one direction. It was a very calm day. I thought the way atti works is that if i fly for example forward and i let go my controls that it doesn't stop but just drifts away. Or just each other direction. I hope this makes sense. Is this normal? Thanks!
