I met Jim Rust at Whirlwind Propeller (KSEE) for a factory tour and he showed me his latest product in development, a new three blade constant speed, and said I could post a few pictures. Note how thin the blade is, that's good for performance. It seems they have invested in technology with a 5 axis mill that produces the hub in one setup for precision parts. My Whirlwind 200RV prop has performed flawlessly for 750 hrs and looks good.
