I read with great amusement the different threads on here in relation to the various firmware upgrades, conspiracy theories and such, then the plethora of responses that all claim to be true. Then some folks jump in with a rehash of something they've read earlier and the snowball just gathers momentum. The end result is that there are so many different stories, theories, scare stories, folks frightened to fly and conflicting opinions. What I'd like to know is, who actually takes their phantom out into a big open space and actually tests the software for themselves? The rumours about 1.6 restricting ascent speed - who has actually tested this? Can you test at different ambient temperatures where you live? I can't - it's a wet winter here - but wouldn't it be better to run a battery or two through and compare to how it felt before before passing judgement and repeating something that has been read and not actually personally tested?
