Model aviation has been a huge part of my life starting sometime before I was 10 years old. The early teenage years were mainly control line flying but I started flying radio control when I was 13 years old; in a few years I was competing in RC pylon racing. More recent years have been RC sailplanes, sport electric RC, and free flight. I have been passionate about promoting the model aviation hobby, especially to young people. I have promoted model aviation through demonstrations at schools, community education classes, parks and rec programs, hobby-shop sponsored STEM program, and through a College for Kids summer class at a local university.

I have reached the largest number of people through my website ( and my mainly model-aviation orientated blog ( that recently exceeded ¼ million views.  I have detailed instructions for a rubber-powered model plane constructed from foam plates and a small amount of balsa, that I call the Fantastic Foam Flyer  (

Another web article I spent a great deal of effort on was Basic Aerodynamics with a Lesson. Through a series of drawings I tried to convey the basics of model aerodynamics with a few sample questions included. I hope that teachers could include this in their lesson plans.

We live in a changing world with new technologies. There are ways to leverage these new technologies to build the hobby, make more people aware of the fun of this type of flying, and serve the community through a wholesome learning activity. How can we involve youth and newcomers in free flight modeling?

Kurt Krempetz of AMA Glider explains why it is important to trim a glider, so that it will be able to make turns while flying, rather than just flying straight. He also discusses the various forces of a glider, such as the lift force and gravity, and the pitch axis.

The Sky Streak is a balsa motorplane that can be easily assembled by just about anyone and can be flown either indoors or outside. Although the stock Sky Streak flies well, there are some special modifications you can make to really enhance flight performance.
