SIG Four-Star 120 Manuals

Introduction First, some history. In June of 1989, SIG Mfg. introduced the FourStar 40 to the modeling world. No, it wasn't an overnight success, but its reputation quickly spread. Novice flyers suddenly looked like pros and experts couldn't believe how slow it could land without stalling. Instructors began calling us with stories about training people to fly R/C with the FourStar 40, even though it's never been promoted as a trainer. Clubs even began using it for one-design pylon races!
