Here is another question related to the low battery issue. I was under the impression the lastest firmware upgrade would let the Naza calculate remaining battery life and put the bird in come home mode if the battery got so low that it needed to return. I know it goes into auto land as I have had that happen a couple of time with my P2. My issue is going to be not to have auto land go off flying over water as I will be flying low. Or if it does have it return first. So how is this setup? I see it in the firmware for return home but am unclear if this includes a low battery issue or if just put into failsafe? Also does anyone know a way to fly and set up my Futaba so once I am flying I can have a minimum low altitude outside a certain range?
