RE: longer range planes
A couple of years ago one of our pilots set up a downlink video camera so that we could fly the plane by looking at a "cockpit" view on the monitor. This was a HUGE 118" TaylorCraft so it was a pretty docile and tame plane to fly. But when trying to fly it from the remote monitor I can safely say that it was probably one of the hardest things that I've ever done in the world of RC. The reason why is because your vision is so limited looking at the monitor. You have no peripheral vision nor can you look around to see anything else, you only get to see what's right in front of the camera. Also you can't "feel" the plane flying like you could sitting in a full size plane. I was able to line up and land, but I was sweating and shaking like a basket case by the time I was finished. The guy who set it all up had the plane's radio and those of us on the remote used a buddy box setup, and I can safely say that if he hadn't done that his plane would have been totalled many times over. I'm just pointing this out because even for seasoned experienced pilots flying remotely like this can be a very difficult thing to do, and would probably be next to impossible for a new pilot.
Hope this helps
