Check out this great post from the winners of the Australian amateur UAV contest--the guys at Dionysus Designs, a Chico, CA-based team who focus on advanced RC technology, aerial photography and now amateur UAVs. They built their own airframes, then modded a beautiful powered glider (shown here neatly packed into a golf case to make the trip) to win best in show. Loads of helpful links in that post, too. Get in touch guys! We can use that sort of initiative here ;-)
Meanwhile, if you want other shots of contestents and UAVs from what sounds like a really sucessful contest, check out the photo archive here.
