After several trouble-free flights, a breakdown occurred: the drone took off like a flash, with the motors at full throttle, and I had to trigger an RTH to avoid losing it. When I managed to bring it back, one of the motors was overheating and burning every time (some screws had come loose inside the motor). Once the RTH did not work because I lost connection (at 10 meters high) and the drone flew very high in the sky, then went in the opposite direction about 300 meters away, but fortunately I miraculously managed to find it in a field next to a building (the battery had QUICKLY drained). Once, while forcing it to land, I even broke one of the landing gears. I cannot understand the origin of this breakdown. I have made dozens of takeoffs and the drone flies like a missile (indoors by hitting the ceiling and outdoors). I have also launched several takeoffs while holding it in my hand, and the motors are abnormally spinning because they vibrate with such a loud noise that I feel like the blades will detach. Should I return the drone and get a refund?

Après plusieurs sorties sans problème, une panne est intervenue : le drone décolle comme un éclair, les moteurs à fond, je suis obligé de déclencher un RTH pour ne pas le perdre. Lorsque je réussi à le ramener un des moteurs est à chaque fois en surchauffe et est brûlant ! (des vis s'étaient desserrés à l'intérieur du moteur). Une fois le RTH n'a pas fonctionné car j'ai perdu la connexion (à 10 mètres de haut) et le drone s'est éloigné très haut dans le ciel puis est parti dans la direction opposée à 300 mètres environ mais j'ai heureusement réussi à le retrouver miraculeusement dans un champs à côté d'un bâtiment (la batterie s'était RAPIDEMENT vidée). Une fois en le forçant à atterrir j'ai même cassé un des trains d'atterrissage. Je n'arrive pas à comprendre l'origine de cette panne, j'ai effectué des dizaines de décollage le drone s'envole comme un missile (indoor en se cognant au plafond et outdoor). J'ai également lancé plusieurs décollage en le tenant à la main les moteurs s'emballent de façon anormale car ils vibrent avec un bruit tellement fort que j'ai l'impression que les pales vont se détacher. Faut il renvoyer le drone et se faire rembourser ?
