I came to know Chuck when I was a college freshman. I volunteered to be my local PRA Chapter's newsletter editor. An unexpected perk of this job was that my P.O. box at school became the recipient of other chapters' newsletters. Among these was Chuck's wonderful Sunstate club bulletin ("bull" for short) It was full of Chuck's technical analysis of gyro design topics.
Although he was friendly with Dr. B., Chuck didn't automatically toe the Bensen party line. He presented the math in understandable terms, and came to his own conclusions. I was taking a couple engineering courses at the time. Chuck's logical and factual approach was recognizable and downright inspiring. I followed suit as well as I could.
In response to a letter I wrote to Chuck about engines (remember letters, boys and girls?), he sent me a multi-page handwritten discourse, in perfect engineer's lettering, complete with diagrams.
Much, much later, I met Chuck in Florida. He helped with our little project at Bensen Days, mapping the propwash of various gyros to see where a H-stab might best be located.
Chuck didn't tolerate the fake-scientific B.S. that we sometimes get fed in this hobby. He didn't play favorites when unmasking assorted nonsense pushed by sellers of homebuilt-rotorcraft goods. Since he never sold gyro products himself, he could afford to be totally even-handed in these critiques.
Personally, Chuck enjoyed playing up his rural southern background (plowing with mules as a kid, chewing tobacco, and the like), while glossing over his PhD in physics and overseas work experience in the corporate technical world. In those respects, he reminded me more than anyone of the character Doc in John Steinbeck's Cannery Row novels.
It takes a masterful grasp of a topic, and a certain special talent, to make complex topics understandable to ordinary folk. Chuck was a genius at that.
When someone I admire dies, the best memorial I know how to provide is to try to adopt that person's best traits myself. But it's too late to start that now with Chuck -- 'cause I've already been trying for decades!
Thanks for all the enlightenment, Chuck.
