Some of the airframes we built when we first got interested in flying were very simple designs sketched on the back of a napkin, and cut from pressboard with a jigsaw. Today, we use computer-aided design (CAD) software to design our frames before cutting them out with a computerized numerical control (CNC) machine. We will touch on many of the popular design types in this chapter, but first let’s take a quick look at how these actually fly.
One common trait you will see with all of these airframes ...
