The Sky Streak is a balsa motorplane that can be easily assembled by just about anyone and can be flown either indoors or outside. It is a free flight aircraft, meaning that once it is launched it flies without any direct control until it lands and you retrieve it. The Sky Streak can also be easily modified for better performance. In this video, Dave Gee, a member of the AMA education committee, illustrates how to modify a Sky Streak.
