Just started flying a Phantom 3 4K a couple of weeks ago. Am having a blast intermixed with the occasional moments of terror. I have a few questions that hopefully some out there have answers for... 1. When flying on a bright day it is extremely difficult to see the screen of my iphone or ipad. Without thinking I'll rotate around trying to find a shadow and of course lose contact with the phantom (moment of terror). I know there are some 3rd party blinders out there. Do they help and any recommendations as to what works best? 2. Do the parabolic reflectors improve connectivity reliability with the phantom? 3. I've started using Litchi and like many of it's features. However I do not know how to set the home point through Litchi nor do I understand what HOME LOCK or HEADING LOCK does. Any help here?
