That's the same group you posted about last February: http://southernoregonrc.com/index.php?topic=874.0 Looks like they were using a regular handycam type camera. Their pilot needs to learn some evasive maneuvers.
Here it is getting shot, the guy is going to get run over by a car before he has to worry about guns... http://www.youtube.com/watch?v=0jI-bVuYXS4&hd=1
It looks like his octocopter took the shot pretty well. He was able to get back and land so it seems that there really is some redundancy in having eight ESCs/motors/propellers.
