@arruntus, I see that your tests went very well and that your enthusiasm exceeds all the limits ....
In short me too, after doing some test yesterday and as good as yours (the H520 kept waddling on site etc ....), I did others today. That happiness, no disconnection, incredible stability despite a small wind of 20 km / h. , Disconnection and reconnection more loss of presets photos and videos, the orbit (manual certe) without Suddenly, trajectories with the cord. Finally I find a good device well stable and confident ..
Certainly, it does not have all the functions and technology that DJI has put in its devices, but a team of glandus can not get to their ankle. If Yuneec decided to make himself Hara-Kiri alone, that's his problem.
Flashback this morning from Radio and H520
In short, What a good device with its firmware 1.7.3-1.42.
(By the way, it may be the only good they have laid)
