There’s a lot of common sense in it, and a lot of honesty too: I well remember the panic I felt the first time my Phantom decided that it didn’t want to listen to my flight commands any longer, and wondering what the hell I was going to do about that. It was just sitting there, around 200 feet above and 100 feet away, over water. Long story short, I figured it out. The memory lingers, though.
The important thing is to fly safe, practice a lot, and learn from the experience of others whenever you can. You’ll get some great photos and videos and have a lot of fun in the process.
