Admittedly I am a noob at the hobby, so bear with me... Does Ground Station work with the P3P, or is it for an older model? I'm confused as I see lots of references to it, but am not sure what the deal is. I've read older models of phantoms allowed preprogrammed flights, but now they don't, but then I see and hear about people using Ground Station, which leads me to believe it's for the previous models or something. Can someone give me the quick and dirty on the whole thing please? Thanks!
