WHEN YOU select a new plane and engine, what criteria do you use? It depends on your ability to fly, of course. It also depends on the performance you expect from a plane and engine. If you are an experienced modeler, of course, you make the choice based on the experience and your judgment. However, the relatively inexperienced probably could use some help. Hopefully, this discussion and the charts will help you make the proper choices. What is performance? Well, it can be defined by many formulae, but they are too abstract for most modelers. Performance can be as abstract as the beautiful sight of a glider just hanging up there, maybe gracefully following a local hawk.
