see the May 69 issue of Model Rocketry at Ninfingers for a buld article on the Infinite Loop. Then check out the Oct 69 issue about how it became a glider (in the Model Rocketeer section).

also check out the Ringhawk ring wing glider in the nov/dec 2003 issue of Sport Rocketry.


here are some patent numbers to look up in google patents:

3264776
4151674
4246721
