I have been with the 1.6 firmware for over two weeks now, and I've had at least 20 long flights with no issues.. No flyaways, crashes, it hovers rock steady, no vibrations, gimbal shake, nothing. All my batteries are on 1.6 too, RC and GO app are on the latest firmware.. I was nervous at first upgrading, but the battery issues in the cold are why I did it, didn't want to risk my bird as I fly in cold weather. So far I'm happy, I'm starting to think that people with issues with 1.6 maybe didn't upgrade correctly? Not trying to be a smart *** at all, just wondering why I have no issues but others do?
