I'm trying to hook up an Aura 5 board in my plane. I watched Josh's video about it and he quickly rattles off what items you need to do the install. He mentions a "satellite receiver" and something about the "protocol of your choice"........ what in the world is he talking about?? What exactly is a satellite receiver? And what is this "protocol" he mentions? Do I need a regular receiver and also a satellite receiver in the airplane in order to use the Aura board? I'm currently using a spektrum AR6610T rx and an AR610 rx.
