Question? I have two barrettes for my P3S and in the past I have read about flyaways due to taking off with a low battery. I was shooting some photos of different locations in my area a few weeks ago and was nervous about not taking off with a fresh battery each time. I would take off at 100% and drain the battery down to 90% then land and go to another location and use the same battery draining about another 10 or 15% then of to another location. I stopped at 50%. Is this advisable?
