I'm posting these two videos to bring attention to dynamic altitude issues; hopefully Yuneec will pick it up. I purchased my H for a lot of reasons and I love it. One reason I purchased my H is for dynamic altitude with the Wizard Wand. I run trails in the mountains and elevation changes play havoc on good single operator shots. Until recently my Solo nor Phantom had dynamic altitude, now they both have it using my barometer equipped iPad Mini 4, which is a pain to drag around. The Phantom and Solo both do a better job at holding a consistent altitude than my H. Reading about the altitude variances users are seeing makes me question the H's baro function. Dynamic altitude does work with my H but it's choppy, not smooth. I'm sure Yuneec has more important things to address like the twitchy movement's and map view(please), but I would like this addressed at some point. The videos speak for themselves, first video is with the ST 16(no baro I believe) and second is with the barometer equipped Wizard Wand.
