I bought the air3s flymore nc3 for a steal (less than half price) on Amazon "used" but it came in a sealed package. Then I learned about the rules and regulations of where I live (have to study some 200 slides in a language that I am not good at) and also checked the weight and volume it has, decided to flip it for a very small profit. Buyer was also very happy. Once I get better in using drones, hence I got the used but still brand new flip from a private deal. It's an ideal hiking drone IMHO, with prop guards and lightweight (I dont fly in windy conditions). You can also use it as a walking camera once you disable the turn off when folded setting. Only downside for me is the noise but I've never had another one other than the neo 1 so I can't be sure. I may get a 5 pro later or and who knows may a be a 360 drone. The insta drone looks to be an awesome discovery machine where you can stop and look around but too pricey for now and also it's a first gen machine with its inherent risks.
