In the past, the team has created an "unbreakable drone" and a teeny-tiny drone fitted with a rocket launcher. But the most recent drone allows its pilot to play paintball -- via remote control. http://news.cnet.com/8301-17938_105-57588945-1/game-of-drones-where-uavs-meet-paintball/
Don't fly it in Oregon or any other state that has or is passing 'drone' laws. Most specifically state that the drone can not be armed.
I agree with Josh. You'd anyone that has been flying long enough to gain the experience those gentlemen have would be a tad more mature and aware of the impact they are having on public opinion. We all need to keep it clean and professional.
