Quite - It has some fancy fangled titanium hub that and withstand the massive forces involved - stunningly awesome chopper.
How do planes fly upside down?

I got one of them.

Excellent, we can have dog fights with my Commanche or my Black Shark... up to you...

But does it fly upside down?
Give it some rigid rotors and you can get pretty close to flying upside down. You have to be a complete nutter though, and be immune to ridiculous cockpit vibration, and not want to land anywhere with your rotors on, and not want a high top speed, and like replacing the hub system every week, and......
It's not practical, but damn it looks cool!
Not necessarily. Its all about angle of attack.

the same way trains run backwards

Reverse gear?
It's not 'all' about the AoA. Indeed AoA comes into it, though the aerofoil camber and also a lot of other factors do too, engine and structural limitations for example.

I think he's suggesting your post implied symmetrical aerofoils were required.
i fly helicopters, and yes, the blade pitch is collective and can usually be changed from 11 to -11 degrees, and usually works when the motor is ran at a constant rate (head hold mode) and then the throttle stick is used for controlling pitch 
(ie center throttle = no pitch, 100% throttle = +11 deg pitch, 0% throttle = -11 deg pitch)
it's an awesome hobby to get into
anyway onto planes, purely based on the aerofoil & how the flaps are designed (aile)

The stunt helis have super-articulated rotors that flip upside down, so the rotors are actuallt he right way up.

ah nice - I've always been keen to try flying a helo. My father was an airforce engineering officer so I grew up around this stuff and have done a little flying in fixed wing. My dads got a few planes and a heli (Rutan Long-EZ, Vari-EZ, Quickie and a Rotorway... possibly an Exec 162 but I can't be sure)
This is the Vari-EZ and you can see the wings to the Long-EZ along the wall.
This is the Rotorway.

Do any helicopters have ejector seats? (Sideways firing, upwards would be messy)
Soldato
They've been trialed - I believe that some combat helis have a system where blast bolts separate the rotors and then the crew are ejected but it's not a common thing.

Ka-50 Hokum/Black Shark and Ka-52 Alligator attack helicopters have operational ejection seats.
The french eurocopter Tiger had them too in the prototype but the Russians stole it in front of James Bond in Goldeneye so the production one doesn't have them anymore

Check this thing out: http://en.wikipedia.org/wiki/File:B-58_Escape_Capsule.jpg
Escape pod for the B-58 hustler - designed to be used high altitude at Mach 2 - awesome!
