Hi folks; I have been looking at your forum for a while, now. I got interested in cardmodeling when Spaceship One claimed the Ansari prize. There was video of the pilot of the second flight bouncing a model of the craft between his hands while in microgravity. I decided that there was probably a model for sale somewhere. A search on the web turned up the fact that the model with which the pilot was playing was made of paper from a downloadable pattern. I downloaded Ralph Currell's pattern (Thank you, Mr. Currell) and quickly realized that I was in way over my head. But my lifelong attraction to aircraft made this a natural thing for me to want to do, when the weather is not so good. More searching lead to easier patterns downloadable for free. As well as those at Fiddlers' Green. I also purchased two copies of an XB-70 model that is also still way to advenced for me. I really have not yet screwed up sufficient masculine plumbing to even begin a first model. I just printed up a very basic XB-70 I have had on the drive for a while that used to be available at: http://www.homepage3.nifty.com/ctri . Though it seems to be gone. The most boot question that I have at the moment is this: what the devil is a PDO file and why can I not open them? I am running firefox under MEPIS LInux. Okay, cover me guys, I'm going in!
