Largely as a result of this thread, I recently built a Bloody Baron using Ross board. It flies great, and I think the Ross stuff just looks better than DTFB when left unpainted. It's nice to work with, too. Hopefully Wal-Mart will keep enough in stock so I can pick up a few sheets now and then. Last time I bought five or six sheets, and it was all they had. We'll see how it works out for durability. I sealed all the edges with hot glue, but I'll be interested to see how well it resists warping due to humidity, wet grass, etc.
Thanks!
