We have finally had some decent weather and I want to take the new Phantom3 for a test run. I have already done some really short flights but when I get ready to go for a long flight I get nervous and come right back. I guess I need to trust the technology but have this feeling that once I get out there it is going to drop. LOL! Does the controller have to have clear site to the phantom in order for lightbridge to work? I see some longer flights on youtube and it seems hard to believe that the pilot would still have a good line of sight?
