RE: how many flights out of a Battery!!!
Science.........what a wonderful invention. Problem I have with it is that no matter how much math you use, or how complicated you make it, something simple will come up and disprove what you spent all the time proving.
I figure that it's nice to know in theory how many flights you can get, but in reality I find a couple minutes checking the voltage of my battery between flights a lot less expensive in the long run.
Just my thoughts.
