Roy Simpson now has a demo version of Model Design 8 for Windows 95, 98, and NT posted on the Dream Catcher web site. You can download the demo program from http://www.dchobby.com/airfoil/ The demo program is complete except that it will only plot airfoils with a chord length of 5.678 inches for single airfoils or root airfoils of a set of ribs. The tip airfoil for a set of ribs will be 4.567 inches. Wing plans will plot at the scale required to print a complete half wing on a single sheet. This program also includes a few airfoils and one Specification File for a sample wing. The Angle Template and the Circles and Ellipses modules are not crippled in any way and will plot full size. The Design module can also be used to calculate the MAC, location of the MAC, location of 25% MAC, location of 39% MAC, wing area, and aspect ratio of wings with up to 5 panels per half wing. Like all Windows program, this one suffers from Windows bloat and the zip file of the installation program is about 2.5 megs. If you too have a slow internet connection and would like a demo program, send me a mailing address and I will mail you the demo program on 2 floppy disks. Model Design 7 is still available for those with computers running MS-DOS or Windows 3.1. The complete program is about 800K and can even be run from the floppy disk if required. A demo version of Model Design 7 is also available from the Dream Catcher web site. Chuck Anderson RCSE-List facilities provided by Model Airplane News.
