I received my Phantom 1.1.1 4 days ago & it has been running flawlessly so far. I can't believe how great this thing flies! I still have the stock firmware (2.20) installed. Should I update to the latest (I think it's 4.02)? I have read people having issues with some of the updates and I don't want to ruining my perfectly running Phantom. The guy at my local hobby store used the old saying "If it's not broken don't fix it" which is something I have always believed in as well. However, if there are benefits to the latest update then by all means I will do the update... Thanks!
