Hello All,

I came across the plans for an interesting Semroc three-stage rocket design, the Cyber III, on pages 4 and 5 of the May 1970 issue of their Astronautic Modeler technical publication (see: www.ninfinger.org/rockets/catalogs/semroc570/570semroc4.html and www.ninfinger.org/rockets/catalogs/semroc570/570semroc6.html ). They make all of the parts for it today, and it would also make a nice Semroc kit (hint, hint!). To print out the Cyber III fin patterns at 100% size, just open the PDF version of the Astronautic Modeler issue (see: www.ninfinger.org/rockets/catalogs/semroc570/570semroc.pdf ) and print them using the "Scaling: None" or "No Scale" options.

To cross-reference between Semroc's old part numbers (given in the Cyber III plans) and their new part numbers at www.semroc.com , here are the old (1970) catalog listings of their nose cones (see: http://www.ninfinger.org/rockets/catalogs/semroc570/570semroc42.html ), body tubes (see: http://www.ninfinger.org/rockets/catalogs/semroc570/570semroc44.html ), and fin stock (see: http://www.ninfinger.org/rockets/catalogs/semroc570/570semroc40.html ).

Enjoy!
