(ie Expired flight battery) [It happens!!] In other words, if you fly 5 miles away and your aircraft looses power, can you fly it to the surface for a safe landing WHILE STILL IN RADIO RANGE? This is what I call Radio Line of Sight (RLOS). For my moderate setup, this would be about 1.5 miles, but does vary with terrain, trees and other RF 'pathloss' variations. I'd also suggest a 10 pound maximum weight for this type of flying for obvious reasons.
Radio range often outshines the video range.
If you dont see what your craft is doing at 1.5 mile you have no control regardless how good your radio link is. So solid video is more important IMHO.
