A little harder, or should I say "different" she flew real smooth and steady. But the ST 16 seems cluttered with to much information, and does not display important information I would like to see, but maybe it's just getting used to it, much different than the Go App. I like to see how much battery % I have, not voltage as voltage can drop fast and that's no good if you are 2k or more out! What I really miss is the GPS Map, seeing where you are on the map and where your home point and the crafts point is! But maybe I just have not found it on the maze of buttons and tabs!
