The Loss of a Great Friend

Whereas this editorial should be a report on the CAFE Green Flight Challenge as promised last month, it is with a heavy heart that I instead dedicate this issue of Experimenter to our good friend and propeller guru Paul Lipps who lost his brief battle with lung cancer during the early morning hours of Sunday, October 9, 2011. For those who may not know who this remarkable and unforgettable individual is, we offer the following series of articles previously printed in CONTACT! Magazine from July 2004 through December 2010, and include some Experimenter articles published during that same period. In short, Paul's unorthodox perspective led him to look at propellers a little differently than most and to design a prop that defies logic at first glance, with performance numbers that are equally unbelievable. But once the design rationale is understood, we would have to wonder why all propellers aren't designed in this manner. Designer of Light Speed Engineering's Plasma Ignition Systems, Paul wasn't only a creative thinker, but also a likeable, compassionate gentleman. The experimental aviation family needs more people like Paul Lipps; he leaves a void that will be difficult to fill.
