This is a Free Flight scale model designed by Detroit Cloudbuster and FAC member Pres Bruning. His hand drawn original drawing was prepared in November 1974. The original 21" span drawing has been redrawn using CAD tools. The original size and structure has been retained. The CAD drawing was prepared to make it easier to use the T-Shirt iron on transfer process for transferring the parts to balsa sheets. It also makes it easier to create ink jet printed tissue for the model. The ink jet printed tissue uses the markings called out on the original plan. The model is a very good flying rubber powered scale model airplane.
The CAD plan was drawn to fit on a 11" x 17" sheets of paper. In addition to the build plan, some assembly illustrations were added to help show how the structure goes together. To be sure the plan can be printed on all printers, it has been broken into multiple sheets of 8.5"x14" (U.S. Legal size). The five plan sheets are created by taping the smaller sheets together. Alignment marks are provided.
The plan package has been saved as a Adobe Portable Document File (PDF). Be sure to set the software to not scale the drawing to fit the page. This will insure that the individual pages will print at their intended size. If you do not have the Adobe Reader software, it can be obtained at no cost from the Adobe website at http://www.adobe.com .
The plan package and parts laid out to print on 8.5x11" sheets of iron on transfer paper or A4 sheets are provided. Layouts for the ink jet printed tissue sheets are provided but will only fit on 11x17" sheets due to the length of the fuselage. The layouts are presented here for your reference and if your printer can accommodate the larger sheet size.
If you have access to a 3D printer, you will find some 3D print files for propellers here. The 6 1/2" three blade prop is well suited for this model.
