So, what keeps a REAL helicopter from performing these kinds of maneuvers? Thrust to weight ratio?? 'Cuz that would be something to see at an airshow!!

P.S.--Although embedded here, this video is best viewed at YouTube in its wide-screen format:

Holy crap, I had to get behind the door to watch that without getting hurt!
 
he is more amazing to see in person. Search around on YouTube, and you may find a video of him that has an over the shoulder look at the joystick movements on the radio, amazing quickness, but very precise as well.

I used to fly a 30 size heli, which was a 4' diameter main rotor and I trashed it a few times just going around the local soccer field and baseball diamonds.
 
Man that dude must have made a lot of expensive carbon fiber confetti learning that routine!
 
The military needs to recruit that guy for their UAV programs!

Some time ago someone posted a YouTube video about Red Bull helo guy going through all sorts of stuff to make his helo do loops and other acro stuff. Took a lot of work and sweet talking the FAA IIRC.

Also, scale does odd things. Forces & weights don't scale up in a linear fashion. If you double the size, you octuple (sp?) the weight carried by the rotor blades.

I'm not a helo guy, but I believe full scale rotor blades can flap into the tail boom if abused. I assume the downward (reletive the helo) deflection while inverted would take some specialized rotor blade or hub assembly.

You just have to pull the blades back into beta... :eek: :rolleyes:
 
The Szabo brothers have crashed 100's of real model helis, and untold thousands of virtual ones on the simulator.

These model heli's have Incredible power to weight (6-7lb, 3-4HP for that electric heli), super stiff carbon blades/frame/tail. Boom strikes used to be more problematic than they are today.

A real heli could be built. Super light weight, small jet turbine with 20 minutes of fuel, I think easily it could hover inverted and do +- 3g maneuvers.

How would you eject/bail out from it though?

It would be interesting.
