Cool! V-1's are neat, I want to build one with a pulsejet sometime too. I figured I would make that launch rail too
Right now I am working on a V-2 rocket, just making the plug for fiberglass molds. It is 7'6" tall and will be powered with a hybrid rocket engine.there are a few picts on my site [link]http://www.rpmodeltech.com[/link]
Good luck with the project, I look forward to seeing some picts here
