    Is there a point to a one-bladed prop? Any advantage?

    It's supposed to be the most efficient way to make a prop. There are lots of discussions on it but there seems to be no general consensus.

    Genes been around a long time. I too think he was being a little careless. I think it surprised him. Flown in and out of there a good bit. Nice little 2200 foot grass strip. The people are friendly. If every airport could be like it we wouldn't be having the declining pilot population we have now.

    I think Gene was just hamming it up a bit when it started, feigning surprise, that was all-

    There are also some single-bladed props that use a teetering hinge at the hub and and a counterweight to create some constant-speed effect without the complication of a true constant-speed prop. In other words, the prop will automatically seek a coarser pitch in climb and a finer pitch in cruise.
    Here's a link to a 1937 article on the Everel prop: http://www.ultraligero.net/Cursos/va...e_una_pala.pdf

    Yeah that is the type of prop on Gene's cub. Pretty nest engineering setup.

    He seemed to be pretty surprised it actually started.

    Sennsenich had one of these one bladed props hanging on the wall in their Lancaster shop with a story next to it.
