Thin air is the question here. I live at @9,000 ft. Is that why it's more stable and reacts better to my controlls in idle up mode(because of more head speed)? I've been getting closer and closer to hovering since I kinda figured out how to use the switch. Just got 2 tp1320's and hs-55's all around. Servo linkage seems a little stiffer now to swash plate.Should it? I have crahshed more than a few times, but still keep trying. No LHS around here, so I have to make the 1.5 hr. drive to Denver to stock up once a month or so. I have already used so many of the tricks and tips from this forum, so keep them coming. Thanks.
