Need ID of old VSC photo

[Elwyn Aud]

I was going through a bunch of old photo CD's and found this one from a VSC from a decade or more back. I think it was built by Bob Hazel. Can't remember the name of the plane though.

The Flapper?

I remember it being way over controlled with that huge segmented elevator.

I will e-mail Bob and see if he remembers.

  The name escapes me, but I'm pretty sure it was a design presented in Air Trails magazine, about 1950. I'll check when I head to the basement today.

Bob Hazel is the builder/pilot.

Not sure of the name, but it was published in Air Trails, Sep 51.  the name, according to the Morris Old Time Stunt Construction Drawings, it was called "Flying Wing".

When it was flown at VSC, it was not heralded for its stellar performance.

   Thanks to Keith for providing the actual issue date, I was able to look it up quickly. It from a series of articles in Air Trails about stunt design, and was an entry to a contest related to it. It was designed by a Mr. James M.Denker, of Egypt, Massachusetts. There was no real name applied to the design, and the heading for the article just says "Aerobatic Aces" and not much in the way of specifics on the design. Lots of formulas and discussion about aspect ratios and wing loadings. Much like a typical day here on Stunt Hanger! I have always been a fan of flying wings, delta shapes and such, and thought about this design quite a bit in my early days and one that might be quite a bit different to take to VSC, just never did get around to it. I still find it kind of appealing, though.

Thanks for the replies. Now I know why i couldn't remember the name.

I am pretty sure I saw an old picture of several St Louis guys holding examples they had built. Bob's did not fly well.  Perhaps the CG was too far back, and perhaps the elevators were not tightly enough hinged.  I drew one up one time, but never built it.  I spent a lot of time trying to figure out a simpler way to move the elevators, without success. Bob's was nicely built and attractively finished, very similar pattern to the picture in the magazine.

Hi Jim,

Did the two sections of the elevator move at different rates?  I have never seen that one before!

Thanks

Yes.  The aft part of that huge elevator moved to a greater angle of deflection than the forward position.  Makes for a curved, highly cambered section.  I saw this thing fly.  Bob Hazel must be commended for trying to even fly it.  It did fly, but rest assured, it will never compete with a conventional OTS design.

 Another great photo Elwyn, thanks for sharing!
