What ever happened to the Benson Gyrocopter, that was always advertised in Popular Mechanics magazine?, this contraption looked like a couple of pipes, with a lawn chair mounted on it!!, did Mr. Benson end up killing himself in this machine?.

Dr Bensen

Igor Bensen passed away about 2 years ago. He was getting up in age and had some health problems.
He closed up shop quite a while ago. Ken Brock was a good friend of Igor's and made improvments to the Bensen Gyrocopter. Unfortunately, Mr Brock was killed in an airplane accident last year. His wife Marie and her sons are continuing on with the business. They can be found on the web at Ken Brock Manufactoring.

A few blokes here fly full size gyo's powered with subaru's a few generations on from the benson

They go really well one guy has over 350 hours in his, apparently you arn't allowed to bunt them or it goes quiet / bad.

Now days they have a partial prerotator to reduce the takeoff roll -car reduction starter are better than the flexi cable driven from the fan belt
apparently cruise around 50 -60 kts , will cope with turbulance better than a microlight, I've seen them decend vertical with a 3 secoond throttle blast to flare / arrest the decent and grease it on with a 5m ground roll in 5 kts.
Mast bumping is terminal / blade seperation,
rotating before head speed is up on takeoff roll is terminal , they go into a ugly roll then the dying chicken routine !

Your flying a fuel tank / seat bolted to a piece of rhs with a fan out the back with one bearing at the top !! sound as dodgey as a chopper !!

Flown smoothly / wisely they rock. .

A Bloke Civera (sp) made several advances in autogyros,we now use on choppers, one I think was inclining the blade pivot to reduce flapping by feathering the blade to reduce angle of attack called Delta something nowadays.
some of his machines might have been used by the us airmail, fuse like a Stearman.
Apparently he claimed his aircraft was unstallable , unfoutunatly he was killed in a airliner crash :-(

You may be able to d'load the old movie clip of a guy jumping from the Eiffel tower with the equiv of a couple of umbrella's, not a good look , didn't catch on !

Benson Gyrocopter

Just thought I'd chime in with a reminiscence. I'm not a pilot...

Harry Wittmer was good friend of mine, more like an uncle, who hired me to work in his Suburban Camera Shop in La Grange, Ill. (suburban Chicago) at age 16 in 1958. He had been a private pilot as well as a photographer and Lake Michigan sailor, loved gadgets, and taught me a lot about photography, acetylene-torch cutting, risk-taking and seat-of-the-pants engineering and mechanics. His British-born wife taught me something about good business sense and proper English.

Harry built a Benson (Bensen?) Gyrocopter in 1967 and became a dealer. I don't know that he ever sold any units, but he plunged into the gyrocopter world with both feet. I had enlisted in the Army Reserve and spent half that year in basic and advanced training, so I missed hanging around with him during much of the time he was building the gyrocopter, but in October 1967, after I got off active duty, I made several trips with him to a grass airstrip west of Chicago. I drove his Rambler station wagon towing him in unpowered tests, and he showed me how carefully he had constructed the thing, with all the nuts wired, etc. You're right -- it looked like a lawn chair tied to a clothes pole or something.

The last weekend I saw him, we tested the engine he had added -- a 90-hp. McCulloch two-cycle, which turned a pusher prop and sounded like a chain saw on steroids -- and taxied the thing, and I think I towed him aloft without the copter powered. He didn't try a powered flight that day, either because the wind wasn't right or because the engine -- as I recall -- was sputtering like crazy. I wouldn't have trusted it, I'll tell you. I did get some nice pictures of Harry in the thing. He had the utmost pride and confidence in it -- said that if the engine quit in midair it would float back down like a maple seed.

The next weekend, I drove up to the Twin Cities in Minnesota to line up an apartment because I was starting a new job there in November. When I got home, my parents told me Harry had taken his gyrocopter up under power for the first time and crashed. He was killed instantly. I never heard the official report; his wife told me he took off, got up to about 100 feet and dove straight in. For some reason, the authorities hauled the wreckage back to their house and put it in the garage, much to her distress. I saw it, too.

I guess I was lucky I went out of town, or I undoubtedly would've seen the crash. I wish I'd tried to talk him out of flying the thing, but I guess he died doing something he loved. He was 55; I was 25.

Bensen "style" autogyros

If you're interested in the Bensen "style" autogyros, that is, the pusher designs, a couple of companies that are still around that produce these in kit form are:

http://www.sportcopter.com

http://www.aircommand.com

For the tractor style autogyro, check

http://www.flygyro.com/littlewing/

You should also check out

http://www.pra.org

There are others out there but some of the links I had bookmarked aren't there any more. The PRA web site used to have a rather extensive list of the experimental autogyros and helicopters that were available in kit or plans form but they've trimmed a lot of that out for some reason.

FWIW!

Fly Safe,
