I am new to the Phantom but I flew it successfully 2 hours after I got it and it flies like a dream....I have about twenty flights under my belt and I am getting familiar and confident with it. I mounted a GoPro, shot video and stills and couldn't be happier with everything so far. However, I do need some advice...I am barely computer literate but I was able to download the assistant software and connect the Phantom but it tells me that I have it update the " firmware" before I can go any farther. My question is this...if I am happy with the way it's flying and have no intention of using the IOC, is it necessary for me to update anything or can I leave it like it is?
