This is the model plane i made with balsa wood, tissue paper, toothpicks, a rubber band and a propeller. I have to give the credit to Darcy Whyte for providing the design & instructions. It flies great and lasts for a long time. search squirrel model plane and go to the rubber-pwer website to make it. All dimensions are in inches. Sorry my posts are getting gayer and gayer, i am having less time to do this.
