Yes, it was a joke I think. But in all seriousness, it doesn't actually prove or disprove anything without the load of a propeller on it.
I am really liking the new distance based intelligent battery failsafe more and more. It is kicking in and landing itself with 8% to 10% remaining on a consistent basis. I've "let it happen" probably 8 or 9 times now and it has done it right every time. I think this will help me not abuse my batteries. I've learned to trust it, and if it starts coming home, I let it.
If I'm going to be doing something where I do not want the shot to be interrupted by the failsafe, I have a flight profile on Solex that will disable it and put the responsibility entirely on me.
