I have had My Mantis Q now for 4 weeks....it is almost virtually impossible to get it top stop floating. Outside flying after compass calibration and remote calibration it still floats a lot....I would not even attempt to fly this drone inside at all. Hopefully they come up with some update to fix this...till then will not fly it or will sell it. I have the Parrot Anafi, Phantom 4 Pro, Walkera Starlight, Mavic 2 Dual Enterprise, Autel Evo , and the Walkera Voyager 4...none of these fly as bad as the Mantis, it is the worst. Most comparable is the Parrot Anafi, it is solid indoors and outdoors, have flown this in same exact locations as the Mantis Q and no problems at all...
