So I have my I1 for about 3 weeks and absolutely love it! Few weeks ago new software gets released. I am not ready to update I1, 2 remotes and 4 batts. When I start the app on my iPad I get the RED comments to update everything, but than I get the GREEN ready to fly. I have had one issue while flying, the iPad says "ATTI MODE" and I lose GPS flying, which I control the I1 and than it goes away and goes back to GPS. Than happens again. Yesterday I got a compass error so I calibrated the compass and than ATTI mode didn't happen on its own. Is it a must to update the firmware, or can I wait till I am more comfortable?
