I thought failsafe was the same as RTH, at least by what the naza assistant states. It shows a diagram of the phantom rising up 20m and then coming back to the home location to land. I was just outside getting accustomed to the modes since I don't use them that much (CL/HL/RTH) and noticed that when I hit failsafe, it slowly moved to me, never rising, never landing. In fact, it started going passed the home point until I regained control. Tried RTH a few times from different distances an that worked fine. Was I wrong in thinking FS was the same as RTH?
