well i'm really interested in model rockets and i figure some others here on ATS have to be as well. the other day surfing though i found this:
www.spacecad.com...
it's a really sophisticated, but still easy to use, program for designing model rockets. it has every available option you could possibly think of.
enjoy!
EDIT: mispelled model in the title...
