I loved the Vulcan as a kid but could never get one to work. As a BAR, I have built several. This is my second attempt. I call it the "Vulcan Trainer" because I decided to put on both cockpits.
I flew it again at a club launch yesterday on a B4-2. There was actually lots of wind and this one did better than expected.
A vid of the flight can be seen here: http://flickr.com/photos/23694991@N03/3282792753/
