Hi Guys,
Dave Scott runs First RC Flight School outside of Green Bay Wisconsin. He is a full size air show pilot in a Pitts Special he built himself. He also writes articles for Model Airplane News. I have taken a couple of his courses and they are very good and instil a real sense of confidence. Here are links to a couple of his articles. They make for interesting reading.
