Actually you DO have to see the drone yourself. I don't think that is good information to be passing on, telling new flyers they don't have to see their drone when flying. The law states that you absolutely have to be able to see your drone during your entire flight. Any suggestions to the contrary to any flyer is not helping any of us to stem greater restrictions of our flying. It may get to the point that we may lose a lot of flying freedom, due to people doing what you are suggesting and having an accident as a result of not being able to see where they are flying in able to properly control their drone.
Any others reading that feel this way, please join in to tell this new member (He only joined on the 4th of March) what is good and bad advice to another flyer.
