I'm sure that most of you are familiar with the foam "chuck" gliders that you can buy from toy and craft stores. They are lots of fun in their intended role, but I've always enjoyed modifying these inexpensive airframes into RC models. My knotted "Airplane!" model from 2014 is a recent example. While my chuck glider projects lean toward the whimsical and unusual, I figured out early on that these same models can also serve as low-stress trainers for new pilots.
The traditional path to earning your RC pilot's wings is to purchase an almost-ready-to-fly kit and then have an experienced pilot provide instruction over the course of several weeks or months. Even though prices for these types of models are as low as they've ever been, the cost of entry is at least $150 dollars…usually much more. That's a significant investment for someone who probably isn't quite sure if RC flying will be something they want to stick with.
Modifying a chuck glider for RC will probably cost about $50 for the airborne components. That is still not an insignificant sum, but it certainly relieves a lot of the crash anxiety that most new pilots feel. Furthermore, you can complete the conversion in a single afternoon. So there isn't much sweat equity required to get off the ground.
