Avoid this company!!
I bought the potensic d80 10 days ago. I only used it twice on the second flight I set it up as normal it had 16 satilites launched it and as soon as it got into the air it disconnected from the controller and flew itself off never to be seen again. The amazon seller just told me to go and look for it as the wouldn't be replacing it or refunding my money. Amazon just said there is nothing they can do and everytime I message potensic they just say don't worry about they will sort it. But don't say how or when. Do your research and look at the 1 star reviews on amazon as this is a common problem with their drones and they refuse to put things right. I've paid £200 for a case a controller and some spare propellers!!
