Would you really want to fly this helicopter?
 

That looks awesome, he's a brave bloke. You wouldn't want to go much higher tho, I wonder what would happen if he tried transitioning into forward flight?! (I guess it would be a very short flight)

A prototype for the Robinson R11? Makes the R22 look positively robust!

Let me know when they film the engine-off landings: that I must see!:\

Lets hope his legs are up for the job when he does a auto in that thing lol.. Cool none the less..

Several years ago I met a Japanese gentleman who had invented something similar - only his had 4 engines. I believe any two could keep the machine airborne, as like this one, it had no blade pitch control.
This one would not survive an engine failure, as lift is controlled strictly by RPM - if the engine fails, the blades will stop pretty quickly, and you couldn't pull pitch to stop the rate of descent.
Neat idea, but don't go higher than you'd like to fall (and have the engine land on top of you, to boot).

The best part!

GREAT! Love it!

/perf

As long as you dont wave your friends when you fly over them I guess you are ok:}

No good for mustering. I'd have all the cows falling over themselves in hysterics.:)

The helmet is a must - if the piston rods in the engine break, they go straight into your skull, and top up the hole with hot engine oil!

Fantastic, but where would you fasten your sandwich box?:D

The Seremet W.S.8 was a Danish invention similar to this one. (You can Google it but there's not much information and no pictures.)
Anyway,I have a picture in my Jane's Pocket Book of Helicopters(1978). It is a single rotor with a tail rotor machine, with no pitch change on the M/R which is 14'9" in diameter. It has similar tripod gear and a 35 hp Kiekhaefer engine behind the pilot with the cylinder pointing to the pilot's left, just above his waist. Max. T-O weight is 330 lbs.

lots of pilot all over the world.
got to grips with r22's,
then moved on the big stuff,
one of the best selling copters
in the world,
but i know what your saying,
but frank knows what hes doing

That has got to be one of the funniest things I have ever seen. :D

And the scariest! I was waiting for the thing to roll over. He must be a very brave pilot.

I bet there would be a problem folding your charts while in flight?

i hear they are currently developing a IFR version.

I'm slightly puzzled why not use one of the many variable pitch props available? Alternately let the blade feather, with a fixed tab holding a constant AOA, to allow autorotation. Wouldn't involve much machining.

However, autorotation will be at about the same rate as a round parachute with diam equal to rotor. That is one small parachute, and you can't roll on landing to dissipate the energy...

I bet it's a two stroke. If you had variable pitch props, then flat pitch at high RPM = no lube = seize-o-matic.

OK forget the 2-stroke. Tooo dangerous. How about electric?
