Finally, read before you ask. The threads have lots of irrelevant stuff in them, but it is the social aspect that keeps the experts coming back. So just ignore the low signal-to-noise ratio in the threads and glean what you can before asking.
I'm a research psychologist, and one of the things I'm interested in is when you are flying FPV, where are you? Physically you are still on the ground, of course, but mentally where are you? I was helping a friend fly using the trainer cord the other day, and my setup allows the FPV person to look into a hooded camera mounted on the transmitter. The antenna for the receiver is in a belly pack that hooks around the FPV person's waist. You have to rotate your body to face the general direction of the plane in order to improve the video reception.
I was the plane spotter and did the takeoffs and landings for this student, and I also gave them directions on how to turn their body when video reception got poor. I would say 'turn left 90 degrees' or 'turn right 45 degrees', but they wouldn't know whether I was talking about their body or the plane.
This reached a hilarious point on a video on the web where the pilot came up behind himself and hit himself in the head. I guess he thought it would be an interesting trick to clip that poor sod standing there not paying attention to the plane...
