    I have sort of. Years ago. As a very young enthusiast back then I bought one and several months later met Bob Hovey at Oshkosh.
    I only "flew" it in high speed taxi and ground effect. Even in cross winds it seemed to handle well. Needed to have a better engine. There are or is a youtube video of one flying.
    There is one at the Battle Creek Aviation Museum here in Michigan..

    Thanks. The only video that I have seen is of straight line flight in ground effect.

    So what was Bob Hovey like? He put out some interesting designs.

    That is a somewhat-recent version of a design I've been working on for a while. It has not flown. Project log here; discussion thread here.

    General configuration and specs are about the same as I posted a couple of years ago in the project log. Performance will of course depend on the final engine selection.

    You're thinking of the Polen Special, which some others have compared it to. There is a resemblance but the mission of this one is quite different.

    Yes it does resemble remotely Polen Special, which was also hot ride. Yours does look better.

    Your airfoil looks cool too, what is it ?

    Thanks. I haven't settled on a foil, but have been using a Riblett GA37-315 for now. The planform is just a plain old straight taper with a shaped tip, but I am working on a version that has a tapered center section and elliptical outer panels.

    That is a neat foil as well.

    Riblett GA 35A 315 or any Riblett airfoil that meets the mission is a good choice. I believe Billski uses a GA 37A 315, and I'm designing with a GA 37A 415 for Light Sport considering stall speed. Orion liked them as well, I believe he said he had a lot of success with the GA 35A 415.

    + on the Riblett `foils. He and I "agreed to disagree" on the 43013. I have both his monographs - recommended.
