Problem with startup. Not happening. After flying for the past 3 months I decided it was time to get out of Phantom GPS mode and graduate to NAZA. I'm on a MAC so the software is not as "flexible" as the EXE files (I think) and when I upgraded both the controller and the copter, I almost had a fly-away (caught the rascal by the landing gear as it screamed by my head). When I realized I better get a bit more experience and went back to revert to the GPS mode, I again went back out and thought I'd be back where I was before the attempted update. The quad had other ideas. It again acted rather rambunctious and I again brought it back to the MAC for what I thought was simple tweaking. Instead, I have a copter that is not seen by the software and when I start it up it simply flashes its ruby front paws (no back lights at all) and serenades me with a constant "BEEP-BEEP-BEEP-BEEP-BEEP-BLEEPING FN BEEP" until I shut it down. Here's the question: is there a way to reset what was a perfectly fine working GPS quad back to wonderfully working GPS mode. Thanks for any insight or recommendations.
