If you’ve never visited George Gassaway’s site, be sure to check it out. There is a ton of useful and interesting stuff there including his award-winning Space Shuttle project, as well as his Little Joe II model projects and comprehensive scale data. Actually, there seems to be a ton of Little Joe II information that has been added since the last time I visited there.
