Is it possible for my friend and I to fly our phantoms at the same time in the same location? I get the feeling that the transmitter signals would interfere with each other even though the transmitters are paired to separate phantoms. It makes me nervous. I've only seen one video on youtube where there are two phantoms flying at the same time and they seem to be doing just fine until one of them crashes. It looks as though it was just low on batteries though. https://www.youtube.com/watch?v=znATkv1ICvs Has anybody else attempted multiple phantoms?
