I couldn't tell you for sure. That's beyond my understanding. When using boosters and only a few feet away the video gets choppy. Mine will say poor quality the whole way out but I don't have any problems. Video and control work just fine. It's a little misleading haha
Can you overnight me 2 more sunhans and charge my card. And I will send back the 2 that I got today and you can credit me when you get them. I'm leaving on Saturday on vacation and needed to get this working as I am meeting other p3 groups to do some tests and long distance flights.
