    The just completed a short 10 minute flight. Once airborne he had his usual deep sound.

    Sorry not the best shots using a 300mm lense to pull in from altitude.

    Is that a myth or has that/can that be measured?

    If Toldjaso sez it is so then it is fact.

    Has the 3-blade been so quickly forgotten? It was very shiny in my recollection. The sound was awesome.

    Friction is always bad... unless it enables something with a bigger effect that offsets the badness. A perfectly slick prop would be ideal, unless there's less flow separation if you add a little surface roughness.

    Fluid dynamics is hard. That's why I'm an EE. :-p

    The three blade prop beat the hell out of Rare Bear's airframe and was a prime candidate to induce control surface flutter. Galloping Ghost showed us what happens with flutter, as did Miss Ashley II. And a few other ones, who were lucky enough to live to talk about it. The motocrosser (forget his name- Mark Hanna was it?- in a P-51?), Miss America P-51 (rudder tab?), Matt Jackson (was it in VooDoo, or some other P-51?).
    I am not sure if I remembered all of those correctly, fellers, feel free to add comments about any of my posts. This is just a hobby that I have very little time to comment on and enjoy.
