Hi, So I'm ready to take the plunge and purchase a phantom 3 but haven't been able to figure out one thing: I know that lightbridge on the P3A allows great video for FPV over a much longer distance compared to the P3S's wifi, but is this only for downlink video? What about the RC controller end? forgetting the video - can the P3A be controlled farther compared to a P3S or is the RC link really the same between the two? Is lightbridge also used to CONTROL the drone or just for the video end? If not, I would assume they would be similar control range in a dense urban environment. Thoughts?
