EDIT: I couldn't get the link right to the Four Star, but the website is [link=http://www.sigmfg.com]www.sigmfg.com[/link]
Click "Fly on in" and then when that opens, go to Sig Catalog at the top, and look to the left and click "Airplanes" at the top of the list and then "R/C BIY Airplane Kits", and you have to look for the Four Star 40, 60 and 120......Hope you find everything....

Hope that helps......If you are gettin the 4*, that is a great flying plane.....
