This month’s column comes from Steve Manganelli of the Silent Electric Flyers of San Diego (SEFSD).
University of California San Diego (UCSD) students shine, and SEFSD hits the TV news!
SEFSD proudly hosted its third UCSD Mechanical and Aerospace Engineering Capstone Design Fly-Off, with seven student teams competing in a high-density/low-density cargo carrying contest. Piloting duties were split between me, Dennis LeBerge, and Jim Bonnardel, who was in his element offering his trademark mix of folksy charm and unshakable optimism: “Yes, everything will fly, no matter how bad the controls!”
Believing the event had real community value, past member Larry Kosta alerted local media—and it paid off! KUSI-TV’s Jason Austell came out early, filming interviews with me and UCSD Lab Manager Paul Arcoleo for Good Morning San Diego, with a second segment airing at 5 p.m. SEFSD was prominently credited, which was a great win for our community outreach efforts.
My May 13 talk to the class on RC modeling mishaps helped somewhat, although most teams still needed tweaks. The Col. El Pollo J. Rosso team, led by Frenchman Johnpierre Khachi, was one of the few that was ready early, allowing test flights the week before. After some nose weight and control adjustments, it flew—until the motor mount gave out on approach. (3D-printed ... not ideal.)
Scoring was based on the cargo box volume and high-density payload. All eyes were on Team 7, with a box three times the size of the others. Nervous whispers of, “If that flies and deploys, we’re screwed!” rippled through the field—and fly, it did! Jim B. nailed the drop almost dead center to wild cheers. Only two other teams managed to deploy at all; mine, not so much, despite five tries.
Professor John Hwang wrapped things up with awards, marking another exciting and impactful SEFSD community adventure.
Enjoy everything you build and fly.
