It’s always fun to peruse the exhibit halls at Sun ’n‘ Fun on the first day of the show looking for products you’ve not seen before. This year, composite propeller manufacturer Sterna Composite Aircraft, a Los Angeles-based company, has brought its full line of products to show at Booth 016, Hangar B. The all-composite carbon fiber propellers from 63 inches to 78 inches in diameter that it is displaying are formed in one piece, with no foam core, and are primarily designed for ultralight, light sport aircraft, and airboat engines.
