A few days back I was looking for any suggestions for a small quad for a guy that has been sick with Lymes disease for over a year. Terrible disease. Anyway he is improving slowly with a lot of different treatments. So I ordered a Cheerson Cx 10 nano quad and prop guard with extra props. The thing takes off fine and you can control it but yesterday it started spinning while flying. Only did that once. This morning I took it out in still air. About three times it just dropped to the ground. A couple of other times, it had erratic glitches while flying. This happens when less than 20 feet away. Anyone have one of these and experience this? This has no camera or wifi. Came with small controller. I bought this with idea it would help to keep his mind active and keep his motor skills in order. But if this is the norm for them, it just might lead to frustration.
