I've seen this recommended several times and I'm trying to understand the logic behind it. In my case, it seems having it on couldn't hurt: New flyer, Phantom 2 V2, no FPV, basic setup. I do not fly that far away but sometimes far enough that I can't see if the lights start flashing red to indicate it has hit the first level. In fact on the few flights I've made I find myself bringing it back just to have a look at the battery indicators. Paranoid much? If it did hit low battery and start to go home, I think I would realize something was going on and could then switch to ATTI and bring it in quickly. This may be a bad assumption on my part. If I have it off, it could hit that level and if it were too far to see it, I would not know and gravity would eventually do it's thing. :shock: Am I missing something?
