Great review. I wonder if lowering the gains (instead of increasing) would help with flying in windy weather. Please keep us posted if you manage to make the bird behave in wind! I am looking closely at all the Alta users because I'm considering purchasing one too so your review was very helpful.
When it comes to winds - I am now flying an X8 with A2 and it's terrible in the smallest possible winds. Flies perfectly in calm weather, though. I was under the impression that Alta would handle winds a lot better since seeing one video review where the guy flew the Alta in really strong winds and it was very stable. Go figure...
