Rktman, There is a lot of detailed information there. I think I would agree with you that strength is pretty important for my application. Frank, I did use iron-on monokote years ago on the Estes AstroBlaster and Dr. John Kallend's LadyHawk years ago. The finished product looked very good, but I spent a lot of time working on the monokote. I am so far happy with the balsa white-glue coated label paper.
