I’m about to order a P3A and have been reading all about it and watching trillions of YouTube videos. One question I have about the live FPV screen on your Android or iPad: is there some kind of overlaid marker on the FPV screen showing where you are from the camera's vantage point?  Like an illuminated box so you can manually steer toward that marker (you) instead of using the map screen.  

How cool would it be if they could incorporate one of thosefly-down-the-box patterns like on commercial aircraft approaching an airport----like a visual glide slope HUD?!!!

Oh you are talking about the advanced ILS in modern airplanes ? well if you opt to get the hdmi board and use an hdmi tv you will see a diamond on the fpv screen showing your home point so you don't have to look at the map overlay.

And to answer your question more in-depth here is one lucky guy showing the hdmi board in action, hell i am buying one when i get to have my allowance LOL
